Give Draisaitl, Hoglander's even strength matchups and see if he scores more.
It's just a little easier to score against 4th liners and 3rd pairing D
Not only this, but the reason the guys on the PP unit are there, generally, is because they’ve got the requisite talent to be the most productive options in that spot. I know we don’t all always agree with our coaches choices, but generally speaking, there’s a reason the guys on the PP are getting those minutes. Yeah, you can say player A had 23 EV goals and 29 PP goals but player B had 24 EV goals (and 2 PP goals). You’re not going to convince many people that that the 26 goal scorer is a better player than the 52 goal scorer, despite him producing same/better at even strength. Additionally, as you pointed out, the guy who had the additional 29 PP goals is playing the toughest matchups because he’s a 50+ goal scorer who is game planned for. The burgeoning third liner who breaks 20G at EV for the first time in his career wasn’t.
