The Boston Bruins debuted a new fourth line and the league should be scared

The Boston Bruins have debuted a new fourth line this year and the NHL should be scared.

The Bruins in the off-season added some size in acquiring Mark Kastelic from the Ottawa Senators.

Kastelic is basically a younger version of a Pat Maroon, or Milan Lucic, and he has been paired on the fourth line with Johnny Beecher and Riley Duran.

This line is going to create a lot of momentum for the Boston Bruins this season as these players are not afraid to throw the body, or even drop the gloves.

Beecher, Kastelic, and Duran all play a gritty type of game that fits in with the Bruins system.
