If the conversation is to be about whether he's laying it on too thick, I think it would be a much simpler discussion. It's become about "thugs" and other concepts with racial overtones (who wants to talk about the position of Colin Kaepernick's fucking hat again?) that are frankly absurd.
I think the fact this his interview just ten minutes later was much calmer speaks to how amped he was immediately following the game more than anything. And he really didn't do anything other than loudly declare that he's proven all his doubters wrong. There was no profane rant, no character assassinations even. Just him saying Crabtree should stop talking about him because he beat him.
Hearing him actually talk about football is very enlightening. He understands the position as well as anyone.
