In some respect, every team in the NFL is one injury away from having their fortunes altered in a drastic way. Here are the players I believe are the linchpins for each team:
New England Patriots: Tom Brady
Without their field general, the Patriots are a team with an above average defense and a decent, but not dominating, running game. A poor man's Chicago Bears, if you will.
Miami Dolphins: Ronnie Brown
Without Ricky Williams behind him, Brown is the Dolphins running game. Perhaps if Duante Culpepper gets healthy and returns to form the Dolphins won't have to rely as much on Brown, but right now, he's the offense.
Buffalo Bills: Willis McGahee
The running game is the key in Buffalo, and McGahee is the workhorse. Without him, the Bills would have to rely on J.P. Losman's passing. A scary thought.
New York Jets: Jonathan Vilma
Averages 10 tackles per game and is the leader of the defense. Particularly now, with John Abraham gone, the Jets could not afford to lose him.
Indianapolis Colts: Peyton Manning
Perhaps the most obvious selection of them all. He's the one who makes the Colts' offense go. When he's not on his game, the Colts lose.
Jacksonville Jaguars: Marcus Stroud
It all starts up front for the Jaguars. Stroud anchors the defense that is the team's strength.
Tennessee Titans: Keith Bullock
The leader of the defense is its only true playmaker.
Houston Texans: Andre Johnson
He's the only player on the roster that teams really fear. When he struggled last year, so did the team.
Pittsburgh Steelers: Hines Ward
Particularly now, with Plaxico Burress and Antuan Randle-El gone, he's the guy that Ben Rothlisberger will depend on the most. He's also the veteran who leads the team by example.
Cincinnati Bengals: Carson Palmer
Could not be more obvious after his injury in the playoffs spelled the Bengals' doom.
Cleveland Browns: Ruben Droughns
Became the team's workhorse last year and will continue to have that role, particularly if Bralon Edwards and Kellen Winslow continue to be hampered by injuries.
Baltimore Ravens: Jonathan Ogden
Has anchored the O line for years, and is still one of the league's best.
San Diego Chargers: Ladanian Tomlinson
Particularly now, with untested Philip Rivers at the helm, LT's productivity is the key for the Chargers.
Oakland Raiders: Randy Moss
There are a lot of "names" on the Raiders, but he's the only player that strikes fear into opposing coaches.
Denver Broncos: Champ Bailey
In an age when the term "shut down corner" has become a cliche, he's one of the few to whom the term really applies. Takes an enormous amount of pressure off of the rest of the defense.
Kansas City Chiefs: Trent Green
Larry Johnson still has Priest Holmes behind him. Chiefs could not afford to lose Green.
Dallas Cowboys: Roy Williams
Without the threat of Williams' big hits, receivers would run free in the Dallas secondary, which has been suspect at times.
Philadelphia Eagles: Donovan McNabb
For all the criticism he's received, he's a special talent who has kept the Eagles in the running for the better part of the last six years.
New York Giants: Tiki Barber
Eli Manning should be very thankful that Barber managed to find the Fountain of Youth.
Washington Redskins: Santana Moss
Clinton Portis has quality backups. Moss is a unique playmaker on the Redskins' offense.
Carolina Panthers: Steve Smith
Without him, the Panther's offense is vanilla and could be very stagnant.
Tampa Bay Buccaneers: Carnell Williams
Quickly became the focal point of the Bucs' offense as a rookie.
New Orleans Saints: Drew Brees
Their fortunes will rise or fall with newly acquired Brees. His consistency, which was Aaron Brooks' weak point, should be very appreciated.
Atlanta Falcons: Michael Vick
Though it remains to be seen if they can win it all with him, and Matt Shaub is a very good backup, Vick is still the player that controls the Falcons' destiny.
Minnesota Vikings: Brad Johnson
Minnesota has put all their eggs in a fairly old basket with Johnson. If he is unable to repeat his play from last year, they're in trouble.
Chicago Bears: Brian Urlacher
He's the heart and soul of the defense, and defense is the heart and soul of the team.
Detroit Lions: Dre Bly
He's an important part of the defense, and the depth behind him is thin and inexperienced.
Green Bay Packers: Brett Favre
No surprise that the State of Wisconsin is holding their breath waiting to hear whether he'll be back.
Seattle Seahawks: Walter Jones
With Steve Hutchinson gone, he's the key to their offensive line. Without him, Alexander struggles and Hasselbeck has to watch his back.
St. Louis Rams: Orlando Pace
Marc Bulger now has a quality back up, as do
Steven Jackson,
Torry Holt and Isaac Bruce. Without Pace to anchor the line, the Rams would be in trouble.
Arizona Cardinals: Kurt Warner
Warner's back-ups have fewer than 100 combined career passing attempts in the NFL.
San Francisco Niners: Derek Smith
With Julian Petersen gone, he's the defensive leader and a key veteran presence on the team.
