Steele doesn't run the read option nearly as well and JB. I think that all goes back to familiarity with the system. JB has been running a similar spread since he was a sophmore in HS.
Steele is a very talented athlete but he may not have enough time to really learn the system and improve his decision making in the passing game.
He will be a very valuable backup QB if he does not win the starting job though.
Also, IMO, if Steele could run the offense with the efficiency and execution that JB showed at times, the offense could be incredible. Jantz is just that talented.
That said, JB will improve and after the bowl win :yes: his confidence will be very high. If JB can improve his deep passes and increase his accuracy in the short game, he should have success matriculating the ball down the field next year.
