People always joke that football is inherently homoerotic and perhaps some of the butt-slapping and crouching under center is, but the rest of the sport is mostly just asexual violence. Oh, and I suppose there is also the terminology, which can get pretty innuendo heavy. For instance, yesterday during the Falcons-Saints game, Moose Johnston said Julio Jones and Harry Douglas were trying to rub each other off to beat the man coverage. Sound strategy. DBs tend to back off receivers if they are doing that to one another.
