I don't think anyone can beat or compete with the NFL, that's red ocean. But the blue ocean is cutting out college and doing that by paying the top HS kids right after prom, no school (only brand building), and getting them into a league where they are year-round coached, trained, and playing with former professionals or recent college washouts until they are draft eligible. IMG and charter schools already do some of that with HS kids. College is the undiscovered country and its governing body, the NCAA, is a stiff model being forced on a dynamic system. I think the colleges are vulnerable and COVID showed it. Top guys who didn't even play last year got drafted. Add in everything we see with the recent article about annual re-recruitment of players, players opting out of bowl games and now entire years, the portal, COVID players being given another year to play, players keeping their likeness and profitting off of same, all of the 5 stars going to the same 4 or 5 schools, etc. I think some business or person will give it a try and who knows, maybe the next Uber is born.
And that's not to say college football goes away. As I said earlier, only the top 100 players or so would likely make the jump to the development league every year. The rest would still play in college and keep the stadiums (mostly) full.
