To a certain extent I think that is what happened to Baldwin. He had NFL level talent against, lets face it, a Big Sky back when all the traditional powers, Idaho, Montana, Montana State, were weak. His kind of gimmicky offenses didn't fare well against P5 defenses.
I think Hauck tried to use his 3-3-5 defense and it didn't work out. Part of it was the talent wasn't there as well. Same with Baldwin.
That being said, I'd still take him back in a second because he is a better OC and HC then the ones we have now by miles. Shit I'd probably choose Hauck over Best.
Some work out fine too in the FBS. Jason Eck is doing fine at New Mexico. Jimmy Rodgers went to WSU now is at Iowa State. A lot of NDSU's former HC are doing fine. Brent Vigen I think will do fine when he moves up.
