I'm always combining the salaries of Beane's free agent signings and dreaming about the one player he could have signed. Same with draft picks, e.g., give up that second rounder AND a third to move up in WR-rich draft.
I think there's a reasonable chance the Bills could turn the season around, but (imho) it would take some bold moves. Trade what it takes--first-round pick included) for a real WR, like Diggs in his prime. Fire or demote Brady and replace him with someone who has some ideas. And just hope (what else can you do?) that Hairston, Hoecht, Obiwan, a rapidly improving Walker, AND--you need still more!--a returning Strong and a revelation at safety in Hancock will bring the defense up to championship level. Beane has been bold at times, and McDermott did fire Dorsey, so maybe?
