@Synyster Idk it's really tough but I don't think the NFL or any other sport has to. Olympics are much harder just because of the nature of the events, best in the world etc
@HannahSky They can't overlook Drug testing, because at least 30% of players are on something off season. Some got caught, some got away with it. You can't overlook that this now man is taking Testosterone at high levels, NFL can't allow that.
@HannahSky AS far as I know, no. There's this one woman (real women) who tried out as a kicker. She was/is really good, the problem is that the kicker has to tackle after the kick, she's way too small to do that.
@Synyster there's a runner in the Olympics that seems like a man and wins but they've heavily tested her and she's a female biologically. It's a big controversy but she appears to be a female.
