Has anyone mentioned OC Andy Ludwig at Utah? Watching Utah's offense this year they look potent. Especially since he uses a lot of 3 tight end sets. He also was a quarterbacks coach during Harsin's playing career at Boise State. He's well traveled but seems to have been able to develop quarterbacks at every school he has coached.
