Yes. They will find indoor facilities to play in. As mentioned on this thread, there are indoor facilities in Evanston, Minneapolis, Detroit, Indy, St. Louis, Syracuse, Fargo, and Cedar Falls. That’s in the greater Midwest alone. I’m sure other northern schools have indoor practice facilities that could be converted into useful enough for televising games.
Football is worth a crap ton of money to the universities, the networks and all of the the rest of the business side of college sports to televise these games. It’s the golden goose for college sports. Gate revenue is among the least amount of cash the games bring in, and location matters less when you’re not worried about getting local fans in the door. The media contracts might even be more valuable in a world where everyone has to watch on TV or streaming devices.
If they can play without serious risk of transmission to the kids and the coaches, they will do it, whenever and wherever and however they can. The rest is for the bean counters to figure out.
