Texas will continue to be mediocre, and ou will have nowhere near the success they had in the Big12. I can understand what you’re saying about most of those teams, but Ole Miss, Arkansas, A&M and Florida would probably cause problems for OSU. OSU does not recruit near a few of those programs as well. Just my opinion with no skin in the game.
Over that group of teams as a whole, if that were our schedule, I'd expect to be .500 or better pretty much every year. None of them would scare me.
