Simmonds wants to fight Stanley, so as soon as the puck is dropped he trips and then crosschecks someone who isn't Stanley, then crosschecks someone else who also isn't Stanley.
So without ever getting close to the guy he's supposed to fight, he takes a stupid penalty (could have been two), ruining our momentum, and giving them another goal.
Dillon on Matthews and the knee on Sandin should have been called. I think the knee on Holl was accidental, and wouldn't have happened if Holl hadn't lost his stick and tried to play the puck with his hand.
