But they lose out on the Tommie Johnnie game. Two years ago, over 37,000 people went to Tommie-Johnnie at Target field. 4 years ago SportsCenter came to SJU for Tommie-Johnnie and it was essentially just like College Gameday. I believe aside from the target field game, the top 5 or so highest attended DIII football games ever have been Tommie-Johnnie at SJU. Thats a big loss for SJU and CSB as well. And the basketball games are pretty big too.
If UST stays in DIII then they can likely find a way to preserve the rivalry but if they go up a level then that is very unfortunate for SJU.
You can't make a decision based on one football game. The whole system is out of whack. Even the high school St. Thomas Academy dominates sports like swimming due to their huge depth. They need to move up as well like they did in hockey (they fought for years to do that).
