I think there will be many fans that will be upset if the Ducks pick Carlsson over Fantilli. Most casual fans don't do deep dives on their own, but they'll view lots of youtubers, the Athletic writers, and numerous mock drafts that all point to Fantilli.
My preference is Carlsson, but that's in a vacuum. With context, Fantilli adds a dimension to our top-6 core of Terry, Zegras, and McTavish. Fantilli doesn't have to be a center with the Ducks if he can't find different gears because he will still bring that much needed physicality, speed, and tenacious game. Verbeek's vision probably has Fantilli as the ideal forward for his team.
