Honestly, in this political climate, often no policy is better than having a policy. If there isn’t a policy then there isn’t one to be enforce on players. And putting an overly liberal participation policy in place risks putting leagues on the radar of anti-trans groups or even the president.
I asked about any updates on policy regarding the inclusion of trans athletes. "Our policy is our practice" is the answer I received. That has been the standard answer for a while. Any changes would have to be in consultation with the NWSLPA.
