He's an offensive coordinator masquerading as a head coach.
You give him a week in the film room and he'll usually come up with something decent for the first half but as soon as the other team takes it away he's a deer in the headlights.
Don't bet on it. Iowa is one of the top 4 in the conference. I could see at least one pick six from Joseph and 10 points might be the ceiling for buckys offense.
