Yeah, I love Thigpen, and I still think no QB in the NFL could have done better last season behind that OL, but he's going nowhere on this team. Haley/Pioli want big, accurate QBs. Thigpen has many virtues, but he's small and scattershot. He'll do well in Jacksonville with their pounding running game and tall WRs.
He'll be missed, but It's better to trade him now for something than to lose him in 2010 for nothing.
