Calder is really hard to predict. I think it highly depends on what team the prospect is playing, how good they are and how much prime minutes said prospect receives. If BUF and CAR aren't tirefires next year Mittelstadt and Svechnikov have a good shot. Maybe even an outside guy like Yamamoto could score 60+ points and be a Calder nominee if he found chemistry with McDavid or Draisaitl. Dahlin could also be really good but it's hard for a defenseman to win the Calder and he's on a pretty terrible team so it seems very unlikely.
