It should be competing for a national title every so often given their conference, recruiting ability, money, etc. Not on a year in, year out basis like Alabama or Ohio State, but definitely here and there. They should also win the SEC West once every few years. Really pretty similar to Tennessee, IMO.
A&M's problem is that other Texas schools like Baylor and TCU capitalized on Texas's extended down period way more than they did, and their down period might be coming to a close.
I don't quite they are UCLA because unlike them, football is actually a priority at A&M. They want to be really good consistently. I think the administration at UCLA can kind of take or leave being very successful in football. If UCLA wanted to do what it takes to have a consistently great program, they could do it too.
