Jon Weisman at Dodger Thoughts sees a pattern in the Andre Ethier kerfuffle:
If the injured baseball player doesn’t feel he can take himself out of action, because of love of the game, or arrogance, or denial, or fear of being labeled a sissy, then management needs to make the decision for him. You can’t rely on the Russell Martins and Broxtons and Ethiers to break “The Code” of manning up. There are a few exceptions to the rule (his name, I believe, is Kobe Bryant), but you need to have the rule.
