Thanks. I found it. But here's the deal....you can't just go to WatchESPN, scroll down to "Browse by Sport" and click on "NCAA Football". That won't work. If you do that, you'll find 100 college football games broadcast this weekend, but you won't find the LA Tech game.
Instead, just keep scrolling down past the "Browse by Sport" option (which includes the "NCAA College Football" option) and scroll all the way down to the "Browse By Channel" option, and select "ESPN3". That's where you'll find an assortment of European Soccer League games, some college Field Hockey games, some Women's Volleyball games, etc... and of course, the LA Tech vs South Alabama college FOOTBALL game.
Apparently our football games do not qualify for the "NCAA College Football" category anymore. But hey...it's there.
