This is major college football, they don't give him more than anyone else at this level. He's missing basic shit. First series he's got Kmet running free down the middle of the field uncovered, doesn't see him. Same thing happened with Tremble against New Mexico. He missed Claypool a number of times for huge gains.
Look at the sophistication of the Oklahoma offense. They have a new QB every year, they know where to go with the ball.
I also don't think this is a two year thing. Book struggled with this stuff last season as well. Saw it against Pitt, USC, Clemson, and every game this season. What we think is regression is just a lack of growth.
