It's gotta be Kane.
Kuch good obviously but little disappointing in the non COVID years and he has had the far superior teammates
Scoring is different now than when Kane was in his prime (and he's still a 90 point player in today's league).
For perspective, Kane tore the NHL a new one in his 2015/16 season. It was his most dominant offensive season of his career and he still only put up 106 points. He'd bea 120+ point player if he was in his twenties right now. Don't let scoring differentials between eras fool you.
Has he really though? Hedman and Keith are close as are Toews and Point and I can't see Stamkos being that much more impressive in the playoffs then someone like Sharp.
Anyway answer is Kucherov due to concistency but Kane is up there aswell.
We are talking about playoffs here so what does that have with anything to do?
Yes, he has... remember Kuch pretty much exclusively plays with guys like Stamkos and Point.
But Kane played with guys like Michael Handzus and post buy out Brad Richards
