OSU has lost their starting quarterback and looks like they'll have to go with Bowman, who is not a runner and they will have to revert to the offense that Hill seemingly prepared for.
With Retzlaff out, BYU will go Bohannen and ARod may decide that he needs to have Bohannen mostly run the ball, with Martin, since he hasn't passed in a game in a couple of years — and let the running of Bohannen take the pressure off the passing game.
Regardless, the second half will be interesting.
