I'm not even certain Bedard will be a center long term - he has some of the worst defensive habits I have every seen, and constantly flies the zone and cherry picks. He's mostly a perimeter player at this point. Luckily, he has that elite deception and skill ala Kucherov and Kane to still be productive from the outside. Maybe he is able to get to the middle a bit more as he matures, but I'm not sure he'll ever have the strength or athleticism to be super effective in the corners or around the net.
Despite his baby face, he's pretty physically mature for a teenager, like Crosby was. They actually had very similar dimensions as teens: Bedard 5'10 185 vs 18 y/o Crosby at 5'11 193.
But while teenage Sid was quicker and stronger on the puck than 99% of the league at 18, Bedard is probably weaker than 99% of the league, and has at best average agility. And I don't think Bedard's frame could really support much more than 190lbs without hurting his agility.
There's no guarantee he'll be better than Jack Hughes.
I do think Bedard can become a better point producer than Hughes, but he's not going to be able to dictate the pace and drive play through the middle of the ice like Hughes.
If Bedard becomes as good as Hughes, Hawks fans should be thrilled with that outcome.
