Here's the basic problem: you have a half dozen conferences, each with individual and separate medical advisors, all getting differing opinions.
The NCAA (or perhaps a sub-group formed by the major conferences) need a single medical board advising them. Because right now you have about 6 groups of medical advisors all looking at the same X-Ray and seeing different things. That ain't gonna work if you want consistency.
Who's right? I dunno. Thing is, when it comes to COVID nobody knows everything. In fact, nobody really knows anything for sure. We simply look at numbers and extrapolate.
I will say this. According to what I read, B1G athletes can keep their 20 hour a week schedule. They can meet, study, train, lift weights, workout, practice and drill.
They just can't play the games against other guys who also test negative. That makes no sense to me.
If the rationale is "we can't afford to test 300 athletes every week just to be able to play sports. Those tests should go to the community at large". OK. I get that.
But if the issue is safety, not money, then I don't see where playing a real game is any more risky than a practice.
Just my opinion
