Brad Marchand made a splash at rookie camp 2 years ago when he dropped the gloves with Jordan Knackstedt on the first day of camp after some chippy play by the compact forward. Well it seems the pest is up to his old tricks. According to Fluto Shinzawa of the Boston Globe, Marchand took veteran blueliner Dennis Seidenberg out at the knees during a scrimmage today, which led to Seidenberg retaliating with a slash to the back of Marchand's leg to send a message to the young prospect about how things work in the big boys camp.
