And you clearly refuse to get it ...
Fred Jackson wasn't just the best player on the Bills roster last year, he was one of the best offensive players in the entire league before getting hurt. It wasn't as if he came out of nowhere either, this guy has been running this hard and this tough since he became a Bill but he's been constantly buried and wasted behind lesser backs and on shite teams.
Jackson got a lot of juice left. And even if he didn't, there's absolutely never a reason for this team to take a RB in the first round of the draft. There wasn't when Spiller was taken and there still isn't now.
