I'm okay with staff changes, but not wholesale like you suggest. we did that with Dooley in 2011 and it was a disaster.
I'm not sure about Jancek yet. To me, the D has played really well for most of the game but then lost it in the 4th. I think this has generally been true with the exception of two drives by Arkansas in this game. But if you look at OU and UF, depth had a lot to do with it.
So a staff shakeup might be the way to go, but IMO it will only get you so far. It also depends on how this season goes. If Butch does a lot worse than expected, what good coach would want to come here? And would he do better than Sunseri did?
The D did not play well last night. Arky stopped themselves more than we stopped them. Their QB missed a lot of open receivers early. We couldn't tackle long hair and the QB all night.
