The sad thing if you're a college football fan--in general, obviously we've benefitted from this--is that the NCAA's dreams of achieving parity are long dead. Three of those top 5 earners were in the playoffs. The rich will keep getting richer, and there's little chance (barring a deal with Nike) that any other teams are going to get in there.
I saw it suggested somewhere a few weeks ago-- and I think it's too late now, DJ's cats are out of the bag--but somebody should have thought of salary-capping some of these things before it got out of hand. The unrestricted flow of money would have ruined the competitive balance in the NFL or NBA years ago, but they had the good sense to cap it. No such luck in college football. There are only a handful of teams that have any real chance at the national title and that's not changing anytime soon.
