Well, he was drafted by Tampa and traded to NE. He only had one year left on his contract, so he set out in free agency. NE has Ridley and Vereen so they didn't need him. Pittsburgh then signed him. He had a 1000+ rookie season, but struggled before the end of last season. Blount also had some aggression issues, as he really got into with a Boise State fan after a game while he was at Oregon. It lead to some punches being thrown. His work ethic was reportedly bad in Tampa as well. So basically, your talented RB that gets in the way of his own success.
