Sherm and Earl talk during the game. Lots of guys talk during the game. Brady talks during the game. You ever seen Phil Rivers play? It's part of the game. It's not that weird. Do they talk more than a lot of guys? Yeah, but they're far from the only ones doing it.
There was nothing that bad about what Crabtree said, that's why I find it so hard to believe that that was all there was to it. If Sherm wanted to talk just to get attention he wouldn't need to scream into the mic like that, he could just post some shit on Twitter or something. There's clearly some bad blood between him and Crabs that goes beyond things that happened this week.
I love sherman, he's exciting and he backs up his play the majority of the time. That being said, I'm not sure what side your on, but I believe you're saying most players leave it on the field. I agree with that, there really isn't a player who doesn't jaw during a game outside of based Tebow and Wilson, but taking it off the field is pretty stupid... regardless it's been entertaining, but Sherman is no question a douche.
