Craig Anderson got hit behind the net by Brandon Prust. Typically, that's something that would lead to a stoppage in play, but not on this Game 7 night. The Ottawa Senators goaltender lost the puck and waited on the ice for a whistle, only to realize it wasn't coming.
Meanwhile, the Rangers had the puck. In particular, defenseman Dan Girardi had the puck at the point, and he had a wide-open net at which to shoot as Anderson remained on his stomach behind the net. Unfortunately for the Rangers, he couldn't put that puck on net.
Should it have been a penalty? I'm not going to give Prust the benefit of the doubt in thinking this was unintentional contact, especially since he seemed to push himself into the hit with his forearm. It probably should have been whistled dead, but at the same time, Anderson probably should have noticed the lack of a call. Lying down behind a play during Game 7, regardless of whether there should have been a penalty or not, seems like a bad strategy.
