Lets take a look at the jump Barkov made in his 4 especially 5th season offensively. Mackinnon became a different player in his 5th season.I like how we already know that Nico is topping out at 60 points even though he is a ~53 point player so far in his career (0.64 ppg) at age 21.
Literally the entire hockey world had Nico and Nolan 1 and 2. There really was not one reputable source that had any of the other guys up there so again, can we please not?
I don't think Nico will reach the peak of either (certainly not Nate), but I could see him becoming a lesser version of Barkov that can put up 70 points consistently in his prime.
