I wrote a bit about Mark Cuban's proposal for a new football league in this earlier post. Tom Kirkendall isn't convinced that the NFL is the competition Cuban is aiming at. He thinks that the NCAA might be the target:
But is the NFL the real competition for this new venture? It seems to me that NCAA football will be the new venture's main competition, particularly for players. Could Cuban's venture be the professional minor league football league that could spur NCAA members to reform big-time college football toward the college baseball model that has been so successful over the past couple of decades?
Certainly there is an inefficiency with the ways many college football players are treated in their labor market while they are in college - especially the most-talented players in D1 ball. But Cuban noted that teams in his league would go after the lower-round draft picks, so I'm not sure how this would make the new league a competitor in the labor market for the talent that otherwise would play D1 football.
In any case, given network effects and the entrenched nature of NFL and collegiate football, I'd be surprised if Cuban's proposal doesn't become more than an academic exercise.
