Underhill: Kellen Moore said he took this job with the idea that Derek Carr would be his QB

For the third time, I don't disagree with that. I'm just curious if he knew. I seriously doubt he would care and is going to bet on his own decision making on who should start, and he should, but I am curious if he knew the situation before he took the job? My bet would be that he did not know since he had many more important things to do that see how the fans feel about each player.
You'd have to ask Moore, not this board, if he knew.

I think it's highly likely that at some point Moore was made aware that fans booed Carr during a game.

I think it's also highly likely that Moore understands that the only way to keep a fan base in your corner is to win a lot more than you lose.
