By the way Marshawn Lynch grabs his crotch to loosen up his tight underpants, not to deride the opposition. I once played with a golfer, almost a scratch player who did the same thing after every shot. Swollen & bruised balls is the most likely cause.
Marshawn Lynch never utters profanity. He is a vigorous supporter of disadvantaged kids in Oakland, CA. He is extremely shy, which explains his reluctance to appear in press interviews.
Swollen balls? I think the Patriots can help with that.
