I think Frost would fail because he is not committed to the run as demonstrated in a few of the losses. He panicks and goes pass happy. He would need to do some hybrid model of old school power and the current system. This is what I thought we were getting when he was hired.
3-9 sucks regardless of your system but running the ball is the way to win in the B10. That’s one of my frustrations with Frost in short yardage. They line up in shotgun and can’t get the tough yard(s). They play soft and don’t put a hat on a hat. If they ran the option to perfection, they would do better than 3-9 IMO
