I'm pretty sure her over-arching point is that everyone wants games and the team to play and - ultimately - it isn't particularly safe for them to do so. And then everyone complains when games are cancelled. As she notes, our men's team has had 6 games cancelled (not their issues, their opponents). They (the women) still practice in masks although it isn't required. FWIW, note she said there are 4 high risk folks on the team, I know Reese is type 1 Diabetic, I don't know the other ailments.
No, I don't think athletes should have any preference for the vaccine. If she feels personally unsafe, then she should take a sabbatical. But I doubt that's really her point. I truly think she is worried about the health of the team.
There is inherent health risk and the risk of canceling games involved in the current state of things and I think it is wearing on coaches.
