the system Kelly wants to run. If Kelly could tailor the offense to be a mostly run based offense that either gave the ball to the running back or the quarterback kept himself, Zaire would have a good chance to win. Throwing the ball is not Zaire's strong suit yet.
However, you need to be a well oiled machine in order to run such an offense effectively. I don't know that our offensive line and everyone else will be on the same page.
So it seems like to me a waste of time to put in a temporary offense for one bowl game.
