I wouldn't worry too much. Just a guess - I'd say 70% of NFL wide receivers are infantile at best, just to pick a number out of thin air.
For some reason, they can't comport themselves as men, choosing to act like 3 year-olds with diaper rash..."Its' All About Me!", armed with money and the usual paid-for predatory posse...
CBs are next in line, followed by RBs.
I love it when on the field, these strutting, preening roosters get their bells rung. It's a dull tone, though.
