I'm advocating for a full bell curve of programs. This will provide more data. Yes, the have-nots have a place. They tend to be fodder, but sometimes upset someone and yank them out of the hunt. Ask OSU.
Limiting it to just one end of the curve will break the sport.
The haves of college football possess the lion's share of the wins, championships, etc, sure, but they also have the majority of the fans (eyeballs, clicks).
You're proposing we saddle half of them with losses they're not accustomed to. Guess what many will do?
Their eyeballs will close and their pointer fingers cease to click.

Go ahead, kill the sport. It's already on it's way.
