I actually thought Dunn improved a lot this season, and showed some big leaps compared to the last 10 years of OSU football schemes. Nardo looks in over his head, but this is data point #1, so its hard to know exactly what he is until another 2 seasons. His first data point is not great, though, so he has a lot of work to do.
If Gundy cared to get OSU beyond our current plateau, he'd take pay cuts from his insane salary and put it towards better coordinators, and if he's allowed to allocate it as such, more recruiting budget. From my seat, it appears he cares more about his salary than winning, because he keeps our recruiting budget low and won't pay top notch coordinators.
