You're bringing this on yourself.
The following are total stats (receptions/yards/TDs) for the first 2 years of each player's career:
Chris Givens: 76/1,267/3
Brian Hartline: 74/1,121/4
Pierre Garcon: 51/788/4
Jordy Nelson: 55/686/4
Eric Decker: 50/612/9
Julian Edleman: 44/445/1
Vincent Jackson: 30/511/6
Brian Quick: 29/458/4
Now, what do all of the non-Rams on this list have in common? Answer: they all had over 1,000 yards receiving in 2013.
Chris Givens had more receptions and yards over his first two seasons than 6 WRs who went on to have 1,000 yard seasons, and yet, he "sucks."
Brian Quick had one less reception than Vincent Jackson, and 13 more receiving yards and three more TDs than Julian Edelman, over his first two seasons, and yet, he's a "bust."
Again... I'm REALLY glad you're not the GM. Some players take longer than others to develop. Right now, the Rams have 5 WRs coming back for 2014 (Austin, Quick, Pettis, Bailey and Givens). They may very well draft a sixth. They could conceivably carry all six, and three to four will see significant playing time. Under these circumstances, the notion of writing off Givens and Quick makes no sense whatsoever, so putting labels on them serves no purpose.
Jordy Nelson needed the best QB and high flying offense in the league.
Decker needed a HOF'er potentially best of all time QB to break 1,000.
Edelman also playing with one of the best HOF'ers of all time.
Garcon being another WR benefitting from a high flying offense and once again, Manning.
You see the trend here? Hartline and VJ are the only two WR's who did it in a similar situation as Givens and Quick.
Just keep digging the hole deeper and deeper.
You probably would have called Isaac Bruce a bust after his rookie year, too.
I have patience. That's not the issue. I'm giving Sam the benefit of the doubt. I've given plenty of guys many years to develop, anywhere from Cliff Ryan to Jason Smith. In football you typically need 3 years to finally understand the game and be ready to produce. That's just the way it is.
I can appreciate the fact that Givens has had some decent production, but they guy will never be a #1. After watching him his rookie year everyone was high on him, with some even saying he could be our #1 which was truly laughable. Football is all about what have you done for me lately. Givens regressed BIG and has no chance vs #1 CB's. He runs sloppy routes and doesn't have good hands. He's 1 dimensional. He can make a career out of it though, think about a guy like Robert Meachem.
Quick was well known as a project coming out. I want to see more of Quick but not at the expense of us getting a true #1 WR.
I wouldn't cut these guys and they provide decent depth, but at the end of the day everyone still wants to add a WR that can be that go to guy across from a consistent weapon in Bailey and electrifying talent like Austin.
