That's an insane ask for a #2C that doesn't really excel at anything sans being the third most important piece to an all time power play.
But agree its not happening so not worth discussing.
He's definitely not the third most important piece on that pp, I'd honestly probably argue he's the most important piece.
He's the lynch pin that makes the Oilers PP tick. The Oilers PP drops higher percentage when he's out by a factor of two compared to one of McDavid or Draisaitl being out. Oilers PP is ~14 GF/60 normally. You take out Nuge? 7 GF/60. You take out one of McDavid or Draisaitl? 10 GF/60.
McDavid or Draisaitl on their own could be the qb of an elite PP. The reason the oilers PP is so good though is because RNH let's them both shine.
A Draisaitl PP would look a lot like the Washington pp has for years. Drai standing in his office ripping one timers. A McDavid PP would look like the Hawks PP where you have a focus on creating and winning small 2 on 1s, creating 4 on 3s or 3 on 2s for strong scoring chances.
RNH let's the oilers PP be both of those at the same time. Normally you can't because large amount of movements are required for one, and static positioning is required for the other. Trying to do both typically means you suck at one and lose possession, or you are very susceptible to pressure and odd man rushes against. But Nuge is simultaneously the oilers pressure relief valve, McDavid's overload running mate, and the guy that always maintains a passing lane for Draisaitl's one timer.
Also worth noting - RNH's red deer rebels team set a WHL all time high for PP conversion at the time, might still be the high water mark. Which is pretty remarkable because that team was pretty much RNH and mediocrity that worked hard. And trust me - I watched him a lot in the WHL, including the entire Oil Kings vs Rebels playoffs series; the oilers were awful and was a good chance they'd draft RNH, and the Oil Kings won the memorial cup that year.
