What he did was wrong! But he pushed the dude not the chick and he happened to fall on the girl.
And the Kick to the girl really wasn't a forceful kick it and I doubt caused a bruise.
Don't get me wrong, I don't condone it but it wasn't a "brutal" attack whatsoever. I believe he deserves suspension but it shouldn't be career threatening. In this day in age, he will face tremendous public blowback and he'll never live it down with a sizable segment of the population, that and his dismissal of the Chiefs and inevitable league suspension should be enough punishment for his actions.
