I hope not, they looked like a line that was doing a lot but truthfully accomplished nothing.
ROR needs to have finishers on his line, he is a puck distributor. Playing with one of the best puck passers in the league and biggest puck hogs (not meant in a negative way) does nothing for ROR. If Marner always has the puck, ROR will never have the puck. JT is a sit in front of the net, try to move my big ass, I'm going to grind along the boards type guy, so is ROR. Seems redundant to have two guys, who play a very similar game, on the same line.
So that leaves him the 1st line, 3rd line or 4th line. Bunting is a similar player in the sense he goes to the dirty areas and is good at 50/50 battles along the boards. I think Bunting works well with AM and WN, not smart to mess with that chemistry.
ROR is IMO better suited for 3rd line duties, it feels like that line is screaming begging for a leader, for a legit center. Engvall and Jarnkrok are both, or can be both finishers, Engvall is not a passer, he is a shooter. PE and KJ are not really get in front of the net take the goalies eyesight away type players, ROR is 100% that guy. I've been wanting a 3rd line that is a threat to score, I think PE, ROR and KJ are that 3rd line.
