Smith finally faced a decent defense and wasn't the same guy people thought he was against Baylor. He played well against Texas, but that's a team where some of the parts are better than the entire unit.
He has 3 more games against good D's - Kansas State (this week), Oklahoma and Iowa State, and one game against an okay D in TCU.
TT set up the gameplan to beat Smith - jam the receivers and run the risk that he beats you deep. So far, he isn't a good deep passer. He struggles when he has to put air under the ball.
The good thing about this season is that Smith has a half a season against good competition to cement being the #1 pick in the draft, or falling like every other QB this year.
Mismanaging the clock.
