I think it’s fair to disregard small sample sizes but 50 games is a pretty significant sample in the playoffs. Especially when Mackinnon has been so otherworldly in them.
He currently sits at 4th all time in playoff ppg. If ppg is not your thing and you would rather focus on the first 50 games of a players career to level the playing field on those who have played in games past their prime, Mackinnon is still ahead of pretty much all comparables. Crosby, Ovechkin, Malkin, Jagr, Kane, Kucherov, Stamkos, Thornton, Zetterberg, Datsyuk etc. I couldn’t find a modern day comparable with a better start through 50 games. It’s not even like he started playing in the playoffs during his prime, he started as an 18 year old and was the best player in the entire first round of all teams that year.
Something that significant can’t be ignored, especially when a guy like Matthews has struggled the way he has to date.
This along with Mackinnons memorial cup (best in modern history) and his play at the World Cup on the “young guns” team (arguably the best player on the team) and he’s building quite the playoff resume. Still missing the big one obviously in a cup, but he has a Conn Smythe written all over him like few ever have.
