I don't agree with this statement (look at Saban at Mich St, for example), but at Texas a good coach should win.
Where did this myth start about Saban failing at Michigan State? He took that program from the toilet and turned them into a strong operation. That was not a big time program at all, and all they ever got was the scraps from Michigan, Ohio State, ND, etc.
Who said he failed? He had one good season at MSU and got a job at LSU as a result.
Dantonio has done a lot better at MSU than Saban. (Dantonio > Saban, just like Fedora > Butch, right, Franchise?)
Michigan State is a B or C level Power 5 program. It's like Pitt, or Oregon State, or Miss State, or NC State, etc etc etc. He built the program there and then moved on.
Not only was MSU 5-6 on the field pre-Saban, but they had a massive scandal that wiped away all the wins of that season. It was an absolute DUMPSTER, and it's a place that will never, ever win a National Championship bc it will never beat OSU and Michigan and ND for the best players.
Compared to Texas which is the number one resources team in America, one of the strongest brands in America, which won 17 games in the 2 season prior to Strong being hired, with several top 10 classes recruited for him awaiting on the team. He then proceeded to complete **** the bed unlike any coach I have ever seen, including Al Golden.
