I don't believe anyone really knows if RS is worth a flip or not. I've never heard anyone define just how much control he had of the offense at UT. I for one always felt CPF was heavily breathing into his headset w every call.
I would have had more respect for RS if he flat out stated he made all calls or if he simply acted as the messenger. Of course, there are always the few calls the headcoach has to make.
RS w/o CPF might be a good fit at MTSU, he's certainly familiar w in state coaches as well as national recruits & brings name recognition to the Blue.
