H.R. 390: College Football Playoff Act of 2009 approved legislation to force college football to ban the promotion of a postseason NCAA Division I Football Bowl Subdivision game as a national championship. The bill favors a switch to a ‘more fair’ playoff system.

I don’t see what the real objection is. Congress has nothing else on its plate now. And anyway, its right there in the Constitution :

U.S. Constitution – Article 1 – Section 11 – Clause 3

The Congress shall have Power To Define and Regulate all Competitive Collegiate Activities that Define a National Champion for the common Entertainment and general Welfare of the United States. All Championship Competitors must be Drawn in uniform throughout the several States, and with the Indian Tribes.

The Congress shall have Power, by and with the Advice and Consent of the Senate, to Declare a National Champion upon Completion of the Competition, provided two thirds of the Senators present concur.

That’s right, the Constitution gives Congress the express power to determine how a college football playoff system should work.
