Sherman own words and explanation makes him classless. Crabtree didn’t say anything to him but pushed him off and walked away and Sherman decides thats enough to go off? He then use the choke sign towards Colin, the game is over he needs to celebrate with his team instead of rubbing it in to the opposing team that just lost on basically a last play of the game. He then explains how great he is.
I guess you didn't hear about Crabtree dissing Sherman all week long.
