If anything keeps Michael Sam out of the NFL, it won't be his sexual orientation
His NFL combine results will have more to do with it...and his numbers aren't great for a defensive lineman.

WEAKNESSES Lacks burst and acceleration off the edge to get a step on blockers and finish. Sack production results from effort and production flushed to him and is not creatively produced with savvy pass-rush moves, speed, power or bend. Average hip flexibility and snap -- struggles clearing his hips at the top of his rush and trimming the corner. Adequate anchor vs. the run. Is late to disengage from blocks. Does not strike with authority. Inconsistent tackler. Late bloomer who could require time to adapt to the pro game.
Their opinion: "Could fit most ideally as a 3-4 outside linebacker in a zone-blitzing scheme like the Steelers or Ravens."
Good news: He came to the combine at 261 - a respectable NFL size.
