Last year, I've got to think he'd have flirted with 100 assists with what McDavid and Kucherov did. And with Karlsson having that 100 point season, I've got to think it even more likely. And he was going to get his share of goals too, so I don't know? Recent years might not be far off of what he got irl. Also consider that medical technology would make his knees better. That could lead to a bit of an increase too.
Ultimately, I think he's the kind of player that would translate well to any era and would dominate any era. And it's important to recall that he was not only numbers. He was solid defense and physical play too. Really an all-around player that excelled in all aspects of the game.
