But doubtful. You would have to show a concerted effort to not schedule or allow BYU into the CFP. That's why the Selection Committee is brilliant. There's no objective data showing who should be in and who should be out. It's all up to the subjective committee - whose opinion cannot be used as a basis for anti-trust violations.
Also, there are plenty of Autonomy 5 teams scheduling BYU over the next decade.
