I think those 2 and potentially Campbell. Campbell has **** the bed lately record wise, but he's been very competitive at times and even won the conference with #50 ish recruiting classes at ISU. If you gave him #25ish Mississippi State type talent, I think he could do well. His teams also play filthy defense which I think is a winning formula at Mississippi State.
Well, really I'm not sure any of those coaches are **** coaches with the exception of Jimbo. Mack Brown is old, and I used to think he terribly underachieved at Texas, but now it looks like Texas is not as easy to win at as you'd think it would be. Malzahn is a good coach. Not great, but good. Kiffin is a good coach. We'll see if he can manage a program long term, which will determine whether he's a really good head coach or just a good playcaller but it looks promising based on his last two stops. Cristobal's record at Oregon looks good and it's kind of ridiculous to be on this list b/c of 2020. Dave Aranda has a pretty short tenure as head coach and I'm not sure what to take from 2020, a good year, then a ****** year. Venebles is too soon to say anything assuming lots of players went with Riley. And as you said, Campbell has had success at a pretty hard place to win.
Looks like this list is a list of coaches that are successful enough to get hired at places that are consistently overrated in the polls b/c of the name on the jersey (ND, USC, PSU, FSU, A&M, OU) and a few examples of somebody being successful enough that the hype outruns the program and it's a credit to them that they even got their program in the pre-season top 10 to begin with (Brown and Campbell), one example of a combination of those factors (Malzahn). Not sure how to classify aranda and Cristobal.
