Different goalies have different syles. Wasn't Patrick Roy a goalie who played with his emotions on his sleeve? It didn't always work for him, but it usually did.
While I agree that Phil sometimes lets his emotions get the better of him, it can also work to UND's advantage. Brad Schlossman said that in UND's game at Bemidji at a time during the third period when the Beavers were getting shot after shot on Lamoureux, after one great save he took the puck to the faceoff dot, slammed it down and gave his teammates a tongue lashing. After that, the Sioux tightened up their defense and kept Bemidji bottled up in their own end for most of the rest of the game.
