It's amazing the retarded excuses fans make as to why they don't want to see a player in a Bills uniform.
Vince Young has won games, something that Buffalo has failed to do consistently in the past decade. He's extraordinarily athletic. I saw him personally at the Ralph run circles around the Bills' defense.
He won't start. Why not let Chan work with him and see where it goes? Worst case, cut him after a year. If he proves to be a problem in the locker room, cut him midseason. Low risk, high reward signing.
