MacKinnon put up some gaudy numbers for three straight playoffs but his team didn't win. He then was as good as he needed to be when they won in 2022. He has been notably been a more consistent all around player than Draisaitl.
Drai's claim to fame is his 2022 playoffs when they Oilers were going flat out full offense which got them one more win than the Avs did in their best playoffs before winning the Cup.
I don't think it's clear at all that Draisaitl, in a vacuum, is the player you want in the playoffs over MacKinnon or Kucherov.
