They provide a noticeable difference in a good way.Mathieu Joseph started his NHL career well. He got the crowd's attention with a hit and drew a penalty in the second period. The hit came when he smashed a Panther against the boards. Joseph drew the penalty when he stole the puck during a penalty kill and started to skate through the neutral zone.Florida goaltender Roberto Luongo had to be helped off the ice after a teammate fell on one of his legs in the second period. James Reimer replaced him. Luongo didn't return to the game.
