This isn't as stretch. He was dealing with an injury last year. If I recall, it was a wrist injury. That explains his lowered goal output.
I'm going to say 50+. He's too much of a game breaker. This is going to be the year, at least production wise, that he cements himself in the conversation with the top 10 forwards in the league. I don't see him getting to that McDavid, Kucherov, MacKinnon, Draisaitl type tier - but I could see him being in the mix with the dozen or so guys right below them who are all perceived to be franchise type producers.
The guy falls down a lot though.
