My own personal philosophy has been that I always give a QB 20 games to make a decision about him. I figure 1 full year(16 games) of starts and then the beginning of the next year to work out the rest of the kinks, is enough time for them to figure out the game and who they are.
Since I'm not counting the Arizona game, this is the last week that I will give Trent a pass as a QB learning the game. I will say that I have liked a lot of what I have seen so far, but I do think that the hit in Arizona has affected him and if he works through it he'll be good.
I think it's going to be a very interesting rest of the season for us Bills fans.
