Not really sure why they are still labelled the first line.
Because they are. They are the go to offensive line at ES and on the PP. 90% of the time they are the first wave on the PP. When the Habs force an o-zone FO, they get it 90% of the time unless they had just previously been on the ice.
The go to offensive line is the first line. It's hilarious that this has actually become a thing now, where people need to deflect from the fact that they are MT's go to line. He leans on them when he needs a goal all the time.
I get why you don't want to call it the first line, doing so changes what we expect from DD-Pacioretty and Gallagher in terms of production, so that when they exceed those expectations you can say, "well look at how well they produce for a second line". They are the first offensive threat MT employs. He does it quite consistently and has done it quite consistently for the better part of two years now.
As well as they are forechecking and playing hard, the third line is getting scored against far too much. As a unit - Sekac, Eller, and Bourque have combined for a -16 rating and 10 PIMs through 6 games, while punching in just 3 points. I know they're our shutdown line right now, but it's simple mistakes that are usually costing us (and not always theirs, the defense hasn't been great).
Outside the Eller giveaway in game 1, I don't recall any goal against that was the 3rd line's fault. Again, yesterday Subban made a bad pinch that led to a 2 on 1. How is this the line's fault? Sekac was even in the process of going to cover point, but Subban made the error before Sekac could even up the rush. On the second minus, they once again stepped on the ice while the play was in progress.
My guess is that MT keeps employing them despite the minuses because he knows that they are not the lines fault. We all know how much of a hardass MT can be when it comes to errors. The fact that he hasn't punished either of the three players suggests that he very well knows that the minuses are matter of ill-timing as opposed to anything egregious in their play.
The +/- is the most misleading stat and carefully analyzing the 3rd line's minuses exemplifies that.
Goal 1 of yesterday. Sekac rings it around the boards for Subban. Two Avs players are close to the puck, Subban pinches anyway. Avs win the board battle, they spring it to a forward which leads to a 2 on 1.
Goal 2: Puck is deep behind the avs net, Galchenyuk, PAP and Plekanec are on the ice. The Avs defender gains control of the puck, the three habs go for a line change. As Iginla received the pass from Duchene just at the defensive blueline, Eller's line comes on the ice, they take enough strides to get passed the blue line, and Duchene tips Iginla's shot. The goal is actually Gilbert's fault as he failed to tie up Duchene who was streaking right between him and Emelin, this allowed him to get some space for a deflection. If you really want to be nitpicky, you can even fault PAP who put 0 pressure on Duchene in his own end and just skated lazily towards the bench. Duchene was able as a result to pick up speed him d-zone and go right between Emelin and Gilbert for a tip.
How are any one these the result of bad defensive ability by Eller's line?
