The Boston Bruins lost a really tight game this week against division rival Montreal. 

The game of course was highlighted by a very controversial offsides call. 

On the ice the play was ruled a good goal but after Canadiens' head coach Claude Julien challenged the call, the refs after a long delay, overturned the goal. 

Bruins' head coach Bruce Cassidy is still upset about the call. 

“They’re over there for three minutes,” Cassidy told reporters. “What is the purpose of this rule? Either you find something [or] you don’t. Three minutes. Now you’re looking for something, for it to be offside. You know it’s going to go the other way, and it did.”

"There was a change this summer, punishing the coaches if they got it wrong for this reason: They didn’t want three-minute reviews,” Cassidy continued. “Anyway, it was a big part of the game. Didn’t go our way.”
