I wouldn't quite say 3rd wheel, but it's becoming clear that Jesse is the heat seeking missile on the line, and due to that he and McDavid are the more likely give-and-go guys in transition.
McDavid's 500's point highlights that. It's Nuge who gets the puck and starts the breakout to Pulju, who drives the middle. A quick give and go with McDavid, and the pucks in the back of the net.
In the O-zone on the cycle I still think McDavid and Nuge like to play catch more, but Jesse's gotten more and more comfortable in that role too as the season has gone on. The one problem all season is that the McNuge combo isn't that effective cycling in the O-zone (compared to their talents) and are normally more dangerous in transition.
I will agree this trio is a waste of RNH, and I don't see why any of Ennis, Neal, Kahun or even Turris couldn't play the same role.
At the moment I think Ennis would be the best fit there, but I'm still going to keep calling for Turris to get a shot. Mainly because I think Ennis is more valuable in the bottom 6 as an offensive spark, and "high offensive IQ player who does the little things right but doesn't touch the puck much" sounds like a fit for Turris.
RNH-Draisaitl-Yamamoto
Turris-McDavid-Puljujarvi
Ennis-Haas-Archibald
Neal-Khaira-Chiasson
Or...
Ennis-Khaira-Archibald
Kahun-Haas-Neal
I'd have time for both bottom 6s.
