The stampede toward league restructuring is happening primarily because of the Supreme Court decision on NILs. It stated that no monopoly can exist to structure college sports, when it comes to player compensation. Moreover, Justice Kavanaugh warned that antitrust lawsuits will be entertained for more than just NILs.

College sports can get around antitrust by forming leagues which do not have identical bylaws. The leagues can argue that players have multiple options where to play. It would be like if the NFL had 3 or 4 other viable competing pro leagues. Or any other business field in which no company has dominance.

That is where a national football playoff and March Madness have problems ... they will be seen as leagues conspiring in concert, a no-no if the leagues want to maintain their argument. So maybe the answer is to have competing playoffs. For example, if there are several basketball playoff structures that would determine their individual champions, then the courts would be satisfied.

Of course, the next step would be for the winning schools themselves to agree with CBS to host a mini-playoff featuring the winners only, without the leagues themselves being involved.
