Again, the basic mistake you and Otto IV are making is to include everyone. When the big change occurs, the bluebloods are going to go off by themselves and leave the rest behind. It will probably come in the form of completely breaking away from the NCAA and not requiring class attendance to play. That is an absolute non-starter to most schools. Plus, a goodly portion of the schools that choose to remain in the NCAA will refuse to play the bluebloods who leave, so schedules won't be padded anymore. Which Week 10 game would you prefer to watch, 3-6 Ohio State v. 2-7 Texas or 9-0 Georgia Tech v. 8-1 Tulane? How would the TV contracts work? One master contract with Fox and Disney/ESPN? Now, you're running up against the Antitrust Act and need the Congressional exemption the pros have. Will they give it?
Promotion and relegation is the stupidest concept in sports. You get to play against the super teams for a year and then go back to playing the teams you usually play. How does that make any sense? You get to see the superstars live once and then you're back down and hoping for that one-year shot again. Most of the yo-yo teams don't have the wherewithal to invest in an attempt to stay with the big guns. And, unless you get a Hollywood personality to buy your team as personal plaything you can only hope to keep yo-yoing each year.
