The guy is an outstanding analyst and also a very good defensive coordinator (2004 Auburn and 2005 Texas).
He can't coach his way out of a wet paper bag as the head coach.
I doubt a spring league has any chance anymore. Remember, when the USFL began in 1983:
- the NBA was just beginning its growth
- hockey was solely a northern game
- March Madness was really just beginning to become a thing, too
- baseball wasn't on 7 days a week save for on WTBS and WGN
All of those will cut into the overall desired audience. Plus, in 1983, the USFL had the good fortune to start after an NFL strike had gutted 1/2 of the regular season so there was more of a "hunger" for football. Also - the NFL wasn't nearly as big in 1983 as it is now, even though it was the #1 sport in America.
I could be wrong - I'd be glad to be wrong - but I just don't think spring football is going to cut it. You have to have time away from a sport and miss it to come back with more interest/emotion the next year (generally speaking).
