The Boston Bruins were without their captain Brad Marchand last night after he suffered an injury in Game 3. In addition to the absence of one of their stars Bruins head coach Jim Montgomery felt the Panthers were getting away with diving to draw penalties, especially after a penalty his player Mason Lohrei was given.
In response to the diving from the Florida Panthers, Jim Montgomery decided to bring it to the referees' attention. To do so he hilariously acted out the Panthers players taking dives in an overdramatic way.
