This is really great for testing mass amounts of people, and it still is really new, but we really need to see what is going to happen on college campuses before we start thinking we could have played games. I bet there will be many more medical advances before the end of this year.
There are colleges that have already had students on campus for more than a week. Let's see how some of these schools handle the first month and see where we are.
My guess is, even with mass rapid testing, we will see outbreaks on teams in the fall. The SEC will change their tune if Alabama or Georgia have starters sit out because of a positive test.
