There's a gay kicker trying to become the first openly gay active NFL player. He was one of the best kickers in all College Football his junior season, but had a few bad kicking games last year. He still hopes he will be picked up by a team.
As for predictions, there hasn't been that much negativity hit the media. The biggest being a college football player saying that football isn't a sissy sport. He later retracted that statement - of course. I hope he got into a lot of trouble. Also, don't expect anyone to come out until after the off-season contracts and rosters are finalized. So it will be a few weeks/months yet. I hope it's soon, I'm curious as to who it is.
