If you’re looking for Nick Suzuki, Helenius is a lot closer.
Catton relies more on his skating, doesn’t really have the grit Suzuki flashes, and lacks the details/nuance (off puck especially) that Suzuki has shown since junior. That being said, I think Catton’s got a higher ceiling offensively with better tools at the same age and isn’t afraid to push things offensively.
I’ve got a personal interest in seeing Catton with the Habs, so I’m avoiding commenting on him very much. However, I will say that I expected him to fill out more through the year and was a bit disappointed with how the playoffs went for him.
