We replaced 3 coordinators and basically lost our d-line. I haven’t seen any evidence that our o-line will be good next year. We also lost most of our running back room. We’re probably not going to be much better next year than this year.
If Coach Ruhl had made more changes after year 1 (OC, special teams) I would be more optimistic for year 3. But after three games, extra practices, and a bowl game (barely) this year, I haven't seen much to make me think things will be that much better next year.
