Sam Leavitt didn't play last week, so his redshirt is still in place. Still think playing him against Nebraska was dumb considering that Noah Kim is still hurt, and QB4 is a walk on freshman. So now if Houser gets hurt you either have to burn the redshirt or play the freshman walk on.
Save that 4th game for now, and either play him, or save him for the final game with no risk. If this is Game 4, I'm fine, because we are losing to Penn State either way, so if you want to play him here, to try and beat Indiana, and then throw the 19 year old walk on out there for what is a loss either way, fine
