Strange that neither are mentioned. Logical explanation is that for Meyer to blame the OC and COC is to blame himself. Not going to happen. TH is certainly not being praised for his contribution to the system (or learning the system).
Further, it is hard to imagine players in a program like Ohio State not even trying hard.
TH was a good guy and good coach, however he often made the mistake of out-coaching himself and over thinking everything. I truly believe that we will see marked improvement offensively due to the simplification of the offense. Thinning the play book will prove to be THE most effective thing that we have done offensively to increase productivity.
