If they win it all this year, they've proven that they can play in a candy conference and only worry about winning the last 6 games against real opponents. Why would they change conferences then? They can just worry about going 6-0 rather than go through a hell schedule in a real conference.
However, if Baylor blows them out, then that's a conversation that will need to be had. Keep in mind, it just took a buzzer beater to beat a power conference number 11 seed. If they barely lose to Baylor, it'll be business as usual. If they get stomped, the conversation will come up, as it should.
