They put in place a ban based on their specific outrage over a law, that law is no longer in place so the reason for the ban has been removed.
Why not remove the ban?
I found it pretty childish to use sports programs that are supposed to be about the sports and players to push political agendas anyway but what more can be expected from those who control the NCAA but to keep up the ban once the law in question no longer exists would be even too childish for them to do.
There is no problem with Trans people using any bathroom they want, there has never been any problem and never will be any problem. This is a lot of crying over nothing.
