Early season LOC is built different.
TMV, what do you mean by that?
I think he's just fresh, he's such an economy of work player, 4th line minutes on full blast make him the most effective. The more he's used the less effective he becomes. Much the same for Cogs really.
I do think LOC has gotten to the point where he can play 3rd line minutes and still be effective, but man when they are really able to play Cogs and LOC as a 4th line they just destroy.
I haven't been impressed with Oo much, but he's not hurting. Hard to look good though after how well Helm centered those two.
