I think Herman was more held back by the talent available than by CPR. CPR wanted him to "run the damn ball" because our QBs struggled mightily to complete more than 50% of their passes.
I honestly think Herman would have done MUCH better the past couple years if he were still here.
I think that, in retrospect, it is clear that a big chunk of the blame lies on contraints from Rhoads. But Herman's problems here weren't just a case of lack of talent. He was unable to utilize the talent he had available and play to their strengths. He was calling plays as if he had five star talent out there rather than calling plays that recognized who was on the field. It is super easy for him to succeed at Ohio State. He's got a soft schedule, top tier recruits, and Urban Meyer. Half of the posters on this board could win 10 games with the situation Hermann has at Ohio State.
