We have a brouhaha brewing in Buffalo folks.(Nice alliteration eh?) Incumbent Fred Jackson feels disrespected, and perhaps he should. He's been the Bills best and most consistent offensive player the last few seasons. And many fans love him. Personally I think he's a nice Running back to have, but he's hardly elite, and he's a guy who can be relatively easily replaced.
Looking at PFF RB projections for 2011(http://www.profootballfocus.com/blog/2011/04/26/2011-running-back-player-projections-ppr-rankings/) they have Jackson ranked 34th, behind such not notables as Tim Hightower,Danny Woodhead,and Mike Tolbert to name a few. Now some will argue that well jackson plays behind a bad line, well so do Steven Jackson,Arian Foster, and Frank Gore, and all three of those players are ranked in the top 10.
Jackson has never scored more than 7 total TD's in one season. He has never had a rushing yards per game average of more than 67 yards per game over a season.(Random example, both Darren McFadden, and Marshawn Lynch have had seasons with better.) He's never had a rush longer than 43 yards in his career.
In my opinion Jackson had 1 great year in 2009, where he was valuable in rushing,returning, and catching. The rest of his career so far can be best described as slightly above average at best.
