Boston's biggest pest seems to be a bit upset over the result of the Stanley Cup Final.

The NBC broadcast caught forward Brad Marchand in tears on the bench at the end of the game.

The rest of the hockey world wasn't too sad to see this reaction from Marchand, who has gained a reputation as one of the most despised players in the league.

Marchand was also emotional in the locker room after the game, telling reporters the Blues "took their dream" from them.

Marchand had a decent series for himself, with two goals and three assists.

He did make a crucial error in Game 7, though.

On the winning goal, Marchand seemed to let eventual goal scorer Alex Pietrangelo freely enter the offensive zone as the Bruins star headed off for a line change.

It's fitting it was Pietrangelo that got past Marchand for the game-winner.

After all, Marchand was the one who had a pretty dirty hit to the knee on Pietrangelo earlier in the series.
