Lynch, like the majority of NFL players has a huge ego - he's too good to abide by NFL rules, after all - he IS Beast Mode. He has a fan base that believes he can do no wrong - why demean yourself by abiding by those overly restrictive NFL norms...so humiliating.
Let it be known however - I like Lynch, I just think he's showcasing his arrogance more than anything. But it's turned into a media buzz - he can profit off it - why not run with it. I don't buy into whatever revolutionary defiance mantra he has.
