Options:
1. Make a huge public statement to the whole world about being gay, and pretend it's not about an agenda, so you don't have to "hide" anymore....basically, be a tool for the cause, promoting and agenda with your private life.
2. Make a private statement to you teammates once you have been selected, and offer to have an open discussion with them privately, in the locker room or whatever, in case anyone wants to discuss it - with the assertion that it in no way affects his ability to play his heart out on the football field, and really should be a non-issue
3. Don't tell anyone a damned thing, becuase it's none of their business. And when they ask what he's doing over the Bye weekend, he says with a straight face, "Steve and I are going on a 3 day cruise", just like any other player would say, "Barbara and I are goign on a 3-day cruise" and leave it at that.
This pretend notion that you **have** to make a big announcement is bullshit, agenda-driven nonsense. If he actually feels that way, it's because the very left-wing groups that claim to support him have brain-washed him in to thinking he is so different and abnormal that he has to pro-actively defend himself, and they are using him as a tool.
Most people don't give a shit. The ones that do will whether or not he makes a public play, or it comes out in the locker room...so the impact between him and other players - which is all that should matter - is the same either way.
