Just kind of a side but I've seen some concerns about Nico being a big riser but then some people would be thrilled to draft Heiskanen at 3, if we hypothetically got it of course. Heiskanen was an even bigger riser than Nico, and arguably really put himself on the radar for such a high selection after a solid U18s.
Point is prospects rise and fall throughout the year, and I get the argument that Patrick is the more "known" commodity but Hischier was still ranked as a mid 1st rounder before the year started. He was known but having a fantastic season in the CHL, plus an amazing WJC will make people that aren't privy to the European leagues really take notice of a guy.
