It's worth to see the plus and minus goals, not just the difference. I took a comparison between the top 10 scorers plus the top three defensemen scorers.
MacKinnon 94-65 on even strength (0 SH goals-5 goals against on PP)
Kucherov 84-80 (0-4)
McDavid 88-57 (1-3)
Pastrnak 72-48 (0-3)
Panarin 63-51 (1-5)
Miller 71-40 (2-5)
Nylander 61-64 (4-5)
Rantanen 83-68 (1-3)
Draisaitl 74-51 (2-3)
Matthews 74-51 (1-5)
Q Hughes 94-56 (2-5)
Makar 68-59 (5-4)
Hedman 73-66 (3-3)
So among the top forwards there are players who have been on the ice on less occasions than McDavid when opponent has scored but none of those has been on the ice as often as McDavid when their team scores.
