If GPS data can reduce injuries enough, would players accept 18-game season?
Will GPS chips soon be a staple of the NFL uniform?
Game Changers Considered At Owners Meetings
International scouting recently drew an NFL general manager to Melbourne, Australia, for a few days of rugby. During a lull in the action one evening, his eyes drifted to the sideline. The head coach was walking to the end of the bench, where a team employee sat holding a laptop computer. The two conferred for a moment before the coach returned to his post and ordered a series of player substitutions.
The next morning, the telephone rang in the Arizona offices of Catapult Sports, one of several Australian-based companies that compile live data on athletic exertion. The general manager was brimming with questions for Gary McCoy, the company's senior sports scientist.
"He wanted to know," McCoy said, "what the hell had just happened."
The general manager will remain anonymous because he did not give Catapult permission to reveal his identity. What he had witnessed, however, was the use of a widely accepted supplement to Australian sports training -- an approach that is beginning to gain traction in the United States.
The coach had viewed a live digital display of each player's exertion and conditioning levels as recorded by a GPS machine embedded in jerseys. The technology added precise data to a decision coaches otherwise make by feel. Who is truly gassed? Who should have the most remaining energy? Who is nearing a danger zone for wear-and-tear injuries?
Rugby coaches in Australia and nearly 400 other sports leagues around the world have incorporated such data into their programs, informing decisions like game rotations, playing time and practice schedules. The goals: maximizing performance and minimizing injuries.
The latter objective is of particular interest in the NFL, which absorbs thousands of missed starts per season and is at odds with its players' union over the impact of an expanded regular season. New NFL Players Association president Eric Winston, in fact, told USA Today last week that an 18-game season is "dead in the water" because of the presumed additional injuries it would cause.
But what if that assumption could be challenged? Could an emerging technology help reduce injuries in the NFL over time? If so, would an 18-game season be more palatable?
The NFL declined comment on a protocol that nearly half its teams have experimented with in recent years. Winston expressed doubt this week that any current or near-future technology could assuage the union's full array of concerns, and a second NFLPA source said it would be a "major leap" to make a positive connection between technology and a longer season.
But a number of NFL coaches acknowledged their growing understanding and use of the data available, and there might be no better example of its potential than the 2013 BCS national champion Florida State Seminoles. Last week, Seminoles coach Jimbo Fisher said his team's soft-tissue injuries, such as muscle pulls and tears, have dropped by 88 percent since it bought the technology two years ago.
"[It] has allowed us to take a lot of the guesswork out of how tired the team is, where your pulls, your tears [are coming from]," Fisher said. "We've been able to apply that and use it full time and gain that information. It's on my desk the first thing when I walk in every day. How we practice, the adjustments I make individually, all that, I live by that thing, and [it's] how we do things. ... I think it's been very critical to our development and our consistency at keeping guys on the field."
Catapult counts 14 teams among its NFL clients, including the New York Giants, Dallas Cowboys, Philadelphia Eagles, Miami Dolphins, Atlanta Falcons, Jacksonville Jaguars, St. Louis Rams and Buffalo Bills. The Seattle Seahawks, meanwhile, consulted with GPSports Systems for similar purposes last season.
Via telephone interviews, McCoy and GPSports athletic performance specialist Rod Lindsell helped construct a framework for how the technology works and the ways it can apply to NFL teams.
Tracking devices measure player movement during training, practice and games, compiling data on running speed, the force of collisions, friction created by the playing surface and more. A total "load score" is calculated and compared to individually designed profiles based on the player's history, giving coaches raw data and context for how much wear the body has absorbed during a day, a week or longer.
"It's basically an athlete's dashboard," McCoy said. "These are elite, high-performance competitors. You wouldn't drive a Formula One car without a dashboard of its performance information. We look at players the same way."
GPS tracking devices produce detailed reports that can be used to reduce the risk of injury.
The idea, as Florida State's Fisher said, is to take the guesswork out of practice scheduling and player maintenance. NFL coaches often change workout routines based on their perception of the team's condition, but this technology offers objective information. (Consider it the difference between feeling the hood of a race car and measuring its engine temperature.)
A player's profile might suggest that a load score of more than, say, 500 for a given week would put him in danger of pulling a muscle or straining a calf. If he has already reached 490 by the end of Thursday's practice, the coach would be well advised to rest him Friday and find a slower pace the following week.
Jaguars coach Gus Bradley embraced the technology after taking over one of the NFL's most injury-plagued teams, in terms of players placed on injured reserve, in 2013.
"So we did the GPS, and we really tried to stay true to it," Bradley said. "If I got the information back from [strength and conditioning coordinator Tom Myslinski] that said, 'Hey, this guy has gotten so many yards in the last two days and it's above what he normally does,' then we taper it back for him. Instead of four out of four reps, he'll get two out of four reps, and we try to stay pretty strict with that."
According to Lindsell, training camp is one NFL tradition that seems ripe for analytic intervention. Even with the dissolution of two-a-days, the still-common schedule of five or six consecutive practices followed by a day off "seems horrible from a structure point of view," Lindsell said.
"We know from the data that high-intensity training for six straight days in any athletic endeavor creates muscle damage," Lindsell said. "As with anything, the body gets stronger by healing itself. It's no wonder you see so many guys with strains and pulls in these situations.
The NFL doesn't allow the use of GPS devices in games, but many teams have started using them to monitor players' practice workloads.
"Think if you were training in a gym, would you do your upper and lower body for six consecutive days? No. You would do upper body one day, lower body another and then maybe cardio. The data suggests taking these principles onto the training field. You would have to customize it to getting ready for a football season, but rearranging the physical emphasis on a daily basis definitely lowers the risk for these kinds of soft-tissue injuries."
During one summer with the Falcons, Lindsell recorded six consecutive days of high-intensity sprinting by a wide receiver. Data showed the receiver was nearing a load score associated with a high chance of a muscle tear. The recommendation was to pull back quickly and allow for recovery.
"It can be pretty obvious when you look at the data display," Lindsell said. "You look at it and say, this is a four-week injury waiting to happen, and really it is completely preventable."
Meanwhile, the Giants contacted Catapult for guidance in making the transition from their outdoor grass practice field to their indoor facility, which has artificial turf. According to McCoy, the technology measured a 15 percent increase in load for Giants players after the shift indoors.
Most coaches know intuitively that turf is harder on the body than grass and try to adjust. But, McCoy said, "when they become aware of the data, they know exactly how much to peel back while not giving up anything relative to performance. So instead of running a drill for 25 minutes, you schedule it for 18 minutes. Or there might be some drills that should be eliminated altogether and replaced by others that make more sense on a harder surface. It's a more precise awareness."
Will it catch on?
The NFL's equipment code doesn't allow for GPS use during games, but that could change. The bigger obstacle is winning over a set of particularly traditional coaches who prefer to trust their instincts on player management.
Fisher's public praise sent waves through the industry last week, and it's well known in America that football innovations tend to bubble up from the high school and college ranks.
"If you present a change in the way somebody does something, there has got to be a reason to change," McCoy said. "We've tried to show the history of what happened over, say, eight years of Australian rules football, where we've seen injury reduction by 35 or 45 percent. A lot of coaches are going to be very, very skeptical about technology, but when you can show them results, that's something that you would think would be of high value to a coaching staff."
Bills coach Doug Marrone, for one, said he uses the data mostly to measure "explosive running." He added, "I'm trying to get a sense from a coaching standpoint how much running is being done during the week and where I have to rest somebody."
Bradley said it can be challenging to limit a player in practice when traditional coaching philosophy preaches the value of repetition.
"The coaches will say, 'Let's get all four of the reps,'" he said. "But I think that comes from me. [I] take the information and say, 'This is the direction we want to go.' Because it doesn't matter. They can practice all they want, but if they're not ready to go on Sunday, it doesn't help us."
A degree of culture change is necessary as well, according to Lindsell. In most professional sports leagues, the equivalent of the strength and conditioning coach has more authority than the NFL's version.
"The model in so many other leagues is to have an athletic performance director who has a real say in, for example, how much volume of work is taking place on a Tuesday or a Wednesday," Lindsell said. "They are the athletic specialists who can best understand, translate and implement the data that's available. Our experience in American football is that it's still controlled by the coaches and that the strength and conditioning guys are limited to what happens in the weight room. That's against our experience in terms of performance and injuries."
Impact on an 18-game season
The decision to incorporate data is traumatic enough for NFL traditionalists. Could it really affect the debate over an 18-game season?
McCoy cautions that, at this point, technology can't slow what sports scientists call ballistic injuries. There isn't much that can be done to soften the blow of a 300-pound defensive lineman landing on a quarterback. Broken bones and torn ligaments remain part of the game and would presumably elevate in prorated fashion if the NFL added two more games.
"No one can really influence that," McCoy said. "But the things that are preventable -- the hamstring pulls, the calf strains, a quarterback's sore shoulder, what we call soft-tissue injuries -- those can all be impacted by smart and accurate conditioning."
The limited scope of impact concerns Winston, who in an interview with ESPN.com said that "health and safety is a pretty broad term."
"I don't think we're necessarily talking about hamstring pulls in the same line as we're talking about concussions and other things like that," he added. "While that all plays into it and soft tissues is a part of it, our 18-game stance has to do with all kinds of ramifications and not just soft-tissue injuries and not just collision injuries. It really has to do with everything.
"While figuring out a hamstring issue is great or figuring out some sort of science behind preventing that, whether it's stretching methods or nutrition methods, it doesn't really get us any closer on 18 games because it hasn't solved a lot of the outstanding medical issues on it."
Thom Mayer, the NFLPA's medical director, said the union "believes that technology can and should be used to improve player health and safety" but cautioned that "any technology used by the NFL or its clubs must be scientifically validated, and any use for health or medical purposes requires the consent of the NFLPA. Our involvement helps ensure that players' privacy is protected and players themselves are involved in the advancement of their health and safety."
Could GPS and similar technology one day mitigate the NFLPA's concerns? Lindsell, for one, takes a global view.
"You have to be smart about it," he said, "but you look around the world at some of the other sports. Take professional rugby, which is a different game, but surely their players are exposed to a lot of collisions. They play 25 or 30 games a year. I understand the NFL is a demanding game, but I don't know that going to 18 games would be overly concerning. You need to run a smart program that takes advantage of the tools that are out there."
It will probably take years of data compilation and results analysis to determine the true impact. Will NFL teams hit the same success rate as, say, Florida State? That's hard to project. But regardless of whether it leads to an 18-game season, the infusion of analytic training is pushing the NFL closer to the rest of the world's elite training methods. That can't be a bad thing.
(Florida State coach Jimbo Fisher credits GPS-based technology with helping the Seminoles reduce soft-tissue injuries by a whopping 88 percent in the past two years.)
If this invention gains traction within the NFL, which it likely will at some point, there shouldn't be much resistance to putting a GPS chip in NFL footballs. Lordy lordy, technology continues its inexorable influence on our lives. Stuff like this makes me fully aware of being an old goat .. Anyone think Jake Long should be wearing one of these? Les and Fish could check in on him daily from their desks. Thoughts?
Re: Has Les Snead Been to Austrailia recently?
interesting idea, i do like that it can force players who can be stubborn to come out since the gps is saying that they may be close to injury
but ya look at how many rugby games are played, compared to how many nfl games played
minutes played a game running: rugby is almost the entire time with 80 minutes a game and a small bit of stoppage for certain phases of the game like scrums and line-outs, nfl has 60, but there's only about 11 minutes of movement, and that's not just running
just look at regular boxing vs well...ufc i guess is the closest to bare knuckle boxing (not counting submissions)
a lot of ufc guys can enunciate during commentary after there careers
even though i don't like the amount of reliance on technology, this probably would help quite a bit
at least SOMETHING will be used to actually PREVENT injuries instead of just hide necessary sensations
a lot of football tackling is aimed at places that normally wouldn't receive a lot of force...i mean the only thing with rugby is the scrums causing spinal injuries...which make sense considering the many head-to-head contacts with the spine taking the blunt of force
though there aren't THAT many...most are freak accidents
in rugby, you should (if you're smart, and you're body will tell you anyway) aim for the softer, naturally cushioned spots of the body and BOTH guys feel the hit
you have guys 50 YEARS OLD on the national rugby team!!! How many guys could be on the "national team" of football at age 50? I doubt any
other than that
rugby tackling > football tackling in terms of technique
gosh, someone's GOT to get in there somehow and fix it
but no, scared parents and $$$$ probably won't let this happen

Not that I'm against this but it just seems like we're getting into the video game mentality.

Re: Has Les Snead Been to Austrailia recently?
I think the league may resist such technology because of the liability implications. A guy gets injured or collapses during camp/practice/a game & there's empirical data to suggest the trainers/coaches pushed him into the danger zone....
Re: Has Les Snead Been to Austrailia recently?
though i don't like to necessary rely on something like this as people are a bit different and can handle different stress levels...it's not a huge difference but still
I think there'd be something the coaches could do to ignore the device in a way....
