I know Alan and he's a great guy first of all! Second of all, I think it is more important to emphasize that his teammates and the administration were supportive of him being gay. I think that is more telling than becoming the first gay athlete in the NFL.
He was supported by his peers because he was a football player. Not because he was gay. Coach Stockstill (his football coach) always had his back and never let anyone say a damn word about his sexuality. That's the way it should be! It also helps the school is very gay friendly and has openly gay coaches, professors and staff members.
The real question is... how does a team's fans deal with the situation? What if he ended up in Carolina? Would they be as accepting as a team in San Fran or NY? That is what I would be concerned about. Nonetheless, I wish Alan the best of luck! He is a great athlete, talented singer and MT's greatest place kicker in school history.
