He scored his only NHL goal on the 3rd line, he played 2 games there before being bumped up to the 1st line (deservedly so) because of strong 2 way play although with Mclellan's constant line shuffling, no line has had appreciable time together.
I don't agree at all with any of what you're saying about his game, although yes he did have a few rough shifts against Nashville as everybody did. His game hasn't been perfect but he's making a lot of great subtle plays that you usually praise players for, you usually have a good eye for the little plays made in all zones. Kid is playing with confidence IMO, getting better and better with each game. He made a boatload of nice defensive reads in the Pens game including the obvious one where he drew the penalty after poking the puck out of the D zone.
I wish there was a shift by shift video of his the last few games so you can see what I'm seeing because I bet that you'd change your mind if you watched it.
As far as Pulju is concerned, he needs to be a lot better. I'm really disappointed that he wasn't able to build on that performance in the Winnipeg game, it's always one step forward five steps back with this player. He's still really young but I'd like to see more consistency with this being his 3rd NHL season and if anything, he's more inconsistent now than he was even in his rookie season. Part of that is on the coaches of course but he needs to start earning his keep. He's getting outplayed by lesser talented players this season, players he shouldn't be getting outplayed by.
