limited ceiling? Interceptions are part of the game. You can't have a passing offense without interceptions. I'll even go a step further and say that the fact that Jake's interceptions frequently come from trying to do too much rather than from poor reads is a positive, because that means he's vastly improved on the mental side of the game.
Is it because he hasn't fumbled in several games, so you have to find something else to criticize him about?
