Bruins head coach Jim Montgomery throws the lines in a complete blender today during practice

Following the Boston Bruins game yesterday against the Philadelphia Flyers, Boston Bruins head coach has made some questionable changes to his lines.

This morning during practice a brawl broke out between Trent Frederic and Parker Wotherspoon, which just goes to show how frustrated players are with how the season has been going.

Jim Montgomery has not helped the cause much as he has not been letting lines play together to gain chemistry with one another, and he's done it once again following a loss.

Montgomery made some big changes this time, and finally broke up the top line of Pastrnak, Lindholm, and Zacha.

Johnny Beecher was promoted to the first line with Pastrnak and Zacha. Lindholm got demoted to the second line with Brad Marchand, and now Mark Kastelic who has been one of the Bruins best players this season.

Charlie Coyle got bumped down to the third line with Max Jones and Cole Koepke, and Matthew Poitras got demoted to the fourth line with Trent Frederic and Justin Brazeau.

No changes were made to the defensive pairings once again.

Do you think these were good changes by Jim Montgomery?
