You're kind of proving a point I have about this center discussion - that folks have a needless fixation on putting the best player at center.
You're saying that Geno is a great player and therefore he should be at center. Being at center should be just about center specific attributes - notably defending down low, starting breakouts low, winning faceoffs. There's nothing wrong with putting the best player at wing, it's not a punishment or a downgrade.
As for Jack Hughes, he's effectively spent much of his career with Erik Haula and others doing much of the center duties for him, even though Hughes is always labeled the center. Perhaps Hughes has it figured out now though, I don't know. People are very obsessed with who is at center, but seemingly mostly obsessed with who is labeled center, and less interested in who is actually doing center things.
Coming back to Catton - someone can correct me if I'm wrong but didn't Catton say he sees himself on the wing? He has a hard time down low defending vs players his own size so putting him in that position in the NHL seems foolish. If he's a center it will likely be a J Hughes type situation where someone else is doing the defending for him, at least for several years. And there's nothing wrong with that, you can have the best offensive player on the wing, there's little lost in doing that. And perhaps something gained, it would save him a lot of energy, Catton wouldn't look as tired.
