Well it now appears that a Caps/Flyers series is imminent. So I give you the Caps/Canadien series as the perfect support for the original stuff posted here. Montreal could not and did not stop Backstrom and he ripped them.
Honestly though, I don't think the Canadiens have the personnel to be able to take out Backstrom, whereas, the Flyers don't really care about playing by the rules and have a few players that would pitchfork people. So there's your key, let's see if the Flyers will do it. Seems a no brainer to me, the Caps don't have anyone that could stand up to the Flyer goons so if the Flyers don't pull that angle they'd be rather dumb.
In case you haven't been paying any attention to the Flyers-Devils series, it seems that would also not be the way to go with the reffing so far. The Flyers are just lucky that the Devils have had a hard time cashing in on their PP, or else this might be an entirely different scenario.
