I think it's more of shock that you would even go to that point.
It's pretty easy to refute. When Jacoby Ellsbury dives for balls, it's because he's trying to record outs, which in turn help his baseball team win ballgames. When Ellsbury tries to steal bases, it's a risky proposition but he's trying to change the outcome of a game, an inning, or even a particular play.
When Kevin Youkilis charged the mound, the play was already dead and its outcome determined. He had been awarded first base. It's not like he was going to be given second base because he charged the mound.
I find every time a player charges the mound to be a selfish act. Crisp acted selfishly last season. The difference? It was the first week of June, and there was still plenty of games to make up for the time that he lost. There was time to make up the ground that could have been lost due to Coco's absence.
Youkilis charged the mound in game number 112. There were 50 games left after his incident, and he was suspended for 10% of them. In a WC race that could be decided by 1 or 2 games, not having your best offensive and defensive player in there for those 5 games could be crucial.
