Suzuki >> Celebrini until proven otherwise, and that may never happen. Your imaginary ceilings mean nothing. Suzuki has the higher ceiling right now, and that has nothing to do with draft pedigree as some players take longer to reach similar ceilings, see the example of Mackinnon vs Crosby to reach a similar ceiling. So nothing you are saying matters until Celebrini proves something, which he hasn't proved to be close to Suzuki yet.
Hutson > Celebrini
That's what matters here. Hutson will win the Calder over Celebrini.
Celebrini is a great rookie and a good centerman already, but comparing him to what Suzuki has become this season is foolish. He has to prove himself, he has to prove he can remain healthy and lead a team. He hasn't yet, but he has lots of time to prove himself.
