Apropos of nothing in particular, but here are select players' (min. 70 GP) statistics in the playoffs, starting from the 2006 playoffs up to 2024, and averaged out to per / 82 GP and then ranked:
McDavid: 41G + 89A = 130 PTS (+31)
Draisaitl: 45G + 74A = 119 PTS (+11)
MacKinnon: 45G + 62A = 107 PTS (+31)
Kucherov: 30G + 64A = 94 PTS (+21)
Crosby: 32G + 59A = 91 PTS (+8)
Makar: 24G + 67A = 91 PTS (+27)
Point: 48G + 42A = 90 PTS (-2)
Malkin: 31G + 52A = 82 PTS (+3)
Kane: 30G + 49A = 79 PTS (+2)
Ovechkin: 39G + 37A = 76 PTS (+2)
Marchand: 29G + 43A = 72 PTS (+16)
Stamkos: 32G + 33A = 65 PTS (-7)
I don't think Matthews / Marner have played enough playoff games to merit fair comparison, but for what it's worth, they would look like this:
Matthews: 34G + 37A = 72 PTS (+3)
Marner: 16G + 56A = 72 PTS (+14)
