Would you have dumped him?

From what I saw, it didn't look like the player threw his equipment to show up the umpire. It was more out of frustration. Tossing the player would acknowledge the fact that the umpire made a bad call and that the player was throwing his helmet over the call, not his frustration. Now if he glares at the umpire and combines that with throwing of equipment, he's gone. Same goes if he says anything. Now the equipment throwing conveys disrespect, not just frustration.

I also didn't perceive the coach's action as condoning the player's behaviour. He got his player under control, probably told him that even umpires are human, and maybe even told him not to throw equipment or make a big scene. Would it have been more acceptable for him to go up to the umpire and chew him out for making what was clearly a bad call? If I'm an umpire in that situation, I would rather the coach quickly get his player to the bench and move on with things rather than giving me grief for missing an obvious safe call.
