Nicklas Backstrom is about as mild-mannered as they come for the Washington Capitals. Forward Troy Brouwer praised him for having a "level head" and insisted the star center won't do anything to jeopardize his teammates moving forward in their first-round series against the Boston Bruins.

But in losing his cool, Backstrom already has. His cross-check to Rich Peverley's face at the horn Monday earned him a one-game suspension and plenty of regret.

"I did what I had to do. I think it was stupid on my part. I've got to deal with it now," a remorseful Backstrom said.
