Have you been seeing people drop the win total or increase?
I honestly don't recall seeing a lot of predictions for next year before Claeys was let go. I was personally thinking 7 wins next year if Claeys stayed (before the suspensions). With all the changes, I'm thinking 6 now.
I don't think we can say how changing OC every year under Brew was detrimental and not realize that this will be the 3rd different OC in 3 years. Plus the whole what happens to the 10 players question. Not to mention some graduations/transfers in key spots that there are at least questions on how they will be filled (QB, C, OT, WR, etc.). Again, the next man up may be even better than what we had, but there are certainly questions. In my mind, especially center and wide receiver. I have zero confidence any WR on the team can reliably catch a ball. Carter, Holland, Gentry, Still, Johnson, etc. have all looked like they have hands of stone at times over the last season(s).
Regarding your original post, I guess if you want call the Claeys regime a new regime from Kill you can. For me, when seven of the ten coaches (plus at least one grad assistant) didn't change, the overall philosophy didn't change, the head coach was the associate head coach and subbed for the previous head coach on multiple occasions, I think it's fair to consider it a continuation of the previous regime. I assume we'll agree to disagree.
