Bean, I think this is going to start up pretty quickly. When the sport is fully professionalized, within 2 or 3 years, max, they'll start this. More TV time and streaming and viewers. They take in more $$$. More advertisers. When the NCAA is pushed out of control of the P2/P3/P4, and the new Super "College Pro" League is formed, the sport will become even more about simply entertainment.
But, yes, I see lower level D1's playing pre-season exhibitions with Super League tams. For so many reasons.
