If I am Brandon Beane, I keep the quarterback that knows the players and system, the Achilles heel is the newly signed QB who struggles for 3 games before he can get you a win. The available QBs are not any better, some are way worse.
So why are Bills fans so down on Barkley ? Because he looked like ***** in a a meaningless game while playing with 2nd and 3rd stringers the last game of the season but they forget how well be played with the starters. Lets also remember Matt Barkley is on the last year of his deal so you will most likely get a well motivated player this year.
