Huh. Interesting. I haven't read a single thing about the guy because I really just don't care and I only watch him play. But yeah, not a chance. Perhaps if he didn't have an absolutely disastrous combine someone might of thought more highly of the guy. Probably the worst area for depth in this draft was on the defensive line... and you combine the fact that he is slow and undersized, you're talking about a guy who is going to be in sub packages playing MAYBE 25 snaps a game.
His ceiling was a 5th round pick, and I believe even before the draft, half the league's GM's said they wouldn't take him until the 7th round or not even sign him... not because he is gay, but because he is what he is, and that is not a prototypical NFL defensive lineman. Good for him if he makes it, but I think he will be the most popular 7th round draft pick cut ever.
I'll go out on a further limb and say he might only have been drafted BECAUSE he's gay. He's not good enough to make a 53 man roster IMO, but I'm not sure the Rams can afford to release him now.
