“Congress being involved” doesn’t mean waving a magic wand and dictating playoff formats or conference inclusions.
The reason there likely WILL need to be some sort of congressional involvement for long term health of CFB is to get an anti-trust exemption, or other statutory exemption.
Pandora’s box of paying players has been opened, and it’s unlikely to me that we will backtrack. There is also the broader issue with media rights sales and collusion between conferences.
By their nature, sports leagues collude with each other and have anti-competitive business practices. MLB, NFL, NHL, and NBA are all exempt from antitrust law for the purposes of collectively selling their broadcast rights.. the MLB has a general exemption from the Sherman act.
The NCAA has been losing lawsuit after lawsuit (starting back in the 80s with the huge TV rights suit from Oklahoma/Georgia).
A solution that involves some kind of “super league,” whether it’s the 30 teams Sankey wants or the 70 teams that most ISU fans would prefer, almost certainly will require congressional action in order to exist because of the nature of antitrust law.
