Not to spoil any fun, but I don't think Marc's really got anything overly special going on. Every St. Louis Ram player looks like he should be a pornstar instead of a football player with their 'bulge'. I think it's just their uniforms that are a little longer down the crotch that makes them look that way. In his West VA days, Marc had nothing down there to draw your eyes.
But if it makes you feel better, here's a peak of his stomach!
Marc Bulger Have no fear, I'll return with more as soon as my computer decides to quit messing with me.
