Blount is certainly one-dimensional, and he can be upgraded if the Bucs go after T. Richardson in a big way. But he's getting too much hate. PFF rated him the 6th most elusive RB of 2011.

He's excellent at breaking tackles in space and it was a big part of his ypc success in 2010. Last year, the Bucs were a trainwreck. Part of that is Blount's motivation, which was awful. He was one of many who quit on Raheem Morris.
I think it's still early to toss dirt on Blount's career or FF prospects in Tampa. No telling how he takes to the new coaching staff, and remember that he was one of only 3 players who personally reached out to new head coach Greg Schiano on the day of his introduction presser.
The Bucs need upgrades on defense badly. I think Morris Claiborne is still in play here, and it may just be that Richardson is gone before the Bucs pick. Watch what the beat writers like Rick Stroud have to say before you write Blount off.
