Not really sure it's up to him. Besides, I think he'd rather win the game than lose cause he wouldn't come out. I think he's a leader, and that he would see the light pretty quick.
Agree that Montez isn't as big as swopes (not sure any QB in college is) but it's the fact that he's a better runner. Also agree it is a role that Awini could fill once he is back, but the other advantage to this is that it would get Montez on the field in more games, not just blow outs.
Not sure getting Montez into games just so he can play running back actually helps him develop as a QB.
