Yeah he'll start in the top-6 and if he isn't on PP1 to start he'll likely get there quite quickly. But he'll need to go PPG if not higher to be our best offensive weapon, and that's a tall order for any rookie. Bedard couldn't do it, P. Kane couldn't do it, Kaprizov, Kucherov, and Panarin couldn't do it.
Don't get me wrong I fully expect him to be very good, and 70+ points wouldn't even be surprising but rookies need time to figure out what works and what doesn't at the NHL, he'll need to adjust to the NHL pace, physicality and rink size and that doesn't just happen overnight, it might very well take 2-3 years in the NHL before his potential is realized.
