Ouch, that's gotta sting! Kreider would’ve been a game-changer for the Bruins. Guess they’ll have to regroup fast.

Tough luck for the Bruins! Kreider in a Canadiens jersey is a sight I never wanted to see. What a rivalry twist!

That’s a major blow! Can’t believe he ended up with the Canadiens. Rivalry just got a bit nastier!
