I'm not sure how Orr is the "perfect" 4th liner. Jay McLement is the perfect 4th liner. A guy who is strong defensively, but has a skill that the rest of the team doesn't that gets him additional minutes on the PK.
Colton Orr is really bad at hockey (relative to his peers). He's not the worst player in the league but he is the worst player on the team. He does provide a skill to the team in that he wins most of his fights but as we have seen from the first 6 games of the year. He fought in one of them. The first fight was a typically 4th on 4th, and the second fight wasn't even really a fight as it was a grab match that led to Parros face-planting on the ice and looking really ugly for the sport.
To me, a good 4th line can fight sure, but they play good defense. Colton Orr doesn't. A 4th liner should have a hockey-related skill that offsets the rest of their game being weak. Orr has that in fighting but nothing else. He takes too many penalties for what he offers back in return. Some of those are "reputation" calls, but they are there because of past experience and it isn't something that is going to change.
I'm ok if he's the 12th/13th forward on the team in general, but I think it is a downright shame that he makes close to a million dollars on a cap-starved team and that superior players get demoted despite superior play. Top 6 forwards deserve leeway and reputation spots on NHL teams. 4th liners shouldn't.
This "muscle matters" garbage is completely overblown. You know what the biggest difference between the Wilson teams that couldn't make the playoffs and the Carlyle team that did?
JVR, Kadri, Lupul, McLement, Franson, Bernier, a good Reimer, a more mature Kessel. But hey, it couldn't be that, it must be Colton Orr's 5 minutes a game.
