He did his time. You might still be upset, understandingly so, but let him prove himself as a guy who doesn't abuse animals anymore. Lets see if he got the message when he was in jail.
As for him playing for the Bills, I don't think he would last long. I think he would get hurt. He certainly is a talent and an above average qb but I would prefer a gunslinger. Someone who would rather throw than run. Hopefully we have that in Brohm. Time will only tell.
