I appreciate getting to hear the uncut version of a player's emotions. More often than not the players just feed the media BS and move on.
Sadly, I think Sherman is an ugly, self-centered person inside. His team just won the NFC championship. Not him. He helped. The first thing out of his mouth was about him being the best CB in the league. Then in the post-game conference, he continues to go on about Crabtree. Then he blogs about it. The media will take it from here.
Crabtree might have said it best: "He's a TV guy. I'm not a TV guy. I play ball. He makes one play and he talks. Good play."
edit:
One other thing. The guy has a knack for catching people at their most vulnerable state and gets pissed when they react negatively. He went to shake Crabtree's hand right as they just lost the NFC Championship game. He also approached Harbaugh right after the September loss. Both received non-favorable reactions. There's no reason to be surprised.
