Actually he ran up to him and said, quote "hell of a game, hell of a game" while extending his hand, that is when Crabtree shoved him in the face and Sherman proceeded to go off from there.
It is on film for everyone to here, I posted a link that has Sherman mic'd up if you don't believe it.
Sherman also said before the series, "They are about to try me and I'm going to make them pay."
