They were cumulative events that were directly related to the choices that preceded them.
- Davis was retained/promoted for harmony/roster continuation during an extremely acrimonious split.
- Sampson was a diversity hire at then-president Herbert's request. He was/is a good coach, albeit with a few scuff marks at Oklahoma.
- Dakich was a stopgap.
- Crean was an attempt to correct Sampson's wayward treatment of a pretty straight-laced program.
- Miller was an attempt to regain connections to the state's HS talent and have a stronger, defensive-minded approach.
- Woodson is obviously brought in due to his connection with the program's past, but I also believe because he has a wealth of knowledge about the game. I don't think he feels he's 'above' the program; but rather a fortunate byproduct of it. (Fair or not, perhaps some of the previous coaches felt* like they could never overcome that element.) Woodson seems extremely comfortable in his own skin and how he wants to run the program as it progresses into the future.
[*I'm make an assumption here off of my perception of their handling of circumstances and could very well be missing the mark. However, I think that the coaches wanted -- rightfully -- to make their own mark(s) and didn't want to be completely indebted to the past.]
