I'm not feeling this one. With Parros and Murray in, Therrien will no doubt try to play the rough stuff and counter Orr and McClaren. Both 4th lines can drop the gloves, so if things start to get sketchy, I'm worried we may see a line brawl. I've never had a problem with fighting, but this is not something Therrien should be thinking. Every single time he tries to match the toughness/fighting game of another team, the Habs end up getting beat, and beaten badly, both in score and in blood.
They need to play with their speed, play smart defensively against Toronto's top line and concentrate on shutting them down in the neutral zone. The moment they are more worried about who wins which fight, they have already lost the game.
