JT Miller and Quinn Hughes are 3rd and 4th in the NHL in powerplay points, does that take away from what they're doing?
No, but they're also not extremely dependent on one another to produce
In my honest opinion, Draisaitl is the same level of player as guys like say Kyle Connor/William Nylander, he just gets a massive boost to his totals because of McDavid and the insane PP percent the Oilers have. He's still an elite player, but you cannot deny that it is largely because of the PP/McDavid.
Over the last 3 years, Draisaitl is
2nd overall in total points (#1 McDavid)
2nd overall in total goals (#1 McDavid)
2nd overall in power play points (#1 McDavid)
6th in even strength points (#1 McDavid)
33rd in even strength goals (#2 McDavid)
Kyrou, Hagel, McCann, Kempe, Aho, Keller, Nelson, just to name a few. All guys with more even strength goals than Draisaitl. There's clearly a massive drop off when it comes to his even strength goals.
Petterson is producing very similar even strength numbers, while being significantly better defensively. Also he doesn't have a McDavid that he's being glued too.
Petterson broke out last year, so comparing the last 2 years (Petterson played 2 more games)
Overall points - Petterson 132 (6th) , Draisaitl 156 (2nd)
Power play points - Petterson 38 (26th), Draisaitl 74 (2nd)
Even strength points - Petterson 84 (7th), Draisaitl 79 (13th)
Even strength goals - Petterson 33 (19th), Draisaitl 22 (77th)
So you have a guy that's producing better 5 on 5 and is literally like 20x better defensively, it's a no brainer.
Once again, the stats and the eye test back up that Draisaitl is in fact a huge beneficiary of the Oilers PP, primarily McDavid.
