It's a tricky spot, regarding the reality show and all of the attention. He is striking when the iron is hot, which you can't really blame him for. If he really did just focus on football, but didn't make the team in the summer, and then tried to go the reality show route, who knows if the interest would still be as high as it is now. Like I said, he is striking while the iron is hot, but he is a fringe NFL prospect already, and having his attention diverted like this is only gonna make it that much harder on himself to make the team.
However, the people who are on the "he only dropped to the 7th round because he is gay" train are missing the point, as he was considered only a 4th or 5th rounder by Mel Kiper BEFORE he did awful in the combine, and if some teams were hesitant about taking him cause of the circus that you knew would surround him thanks to the media, can you blame them? Certainly not. That is one of the reasons Tebow can't get a job in the NFL anymore (although not good enough to start, he should still be able to be a good backup or role player, but it's not worth dealing with that kind of circus for a guy who is just a backup). The same thing will likely happen with Sam, unfortunately.
