Could this now MAN play in the NFL? What about PED test? Do you think they should make an exception?

The percentage of folks who make the NFL is very very low. I doubt given age and how long it would take to achieve the equivalent physique they'd likely be past their prime. So I wouldn't anticipate this being a problem at least in the near future. But I understand where you're going with this. I thought I read where a man who transformed to a woman won a cycling championship. This same type of question was posted. In physical types of sports I could see the man to woman issue being much more prevalent.
