They probably won’t be right if that’s the case. He could play in the top pairing in sense where he is the supporting defender for someone who is actually a true #1 D. Like Muzzin was for Doughty or Brain Rafalski was for Nick Lidstrom.
If they thought he’d be a true #1 all situations elite defenseman, I think their expectations were a bit high.
Teams are looking for players to fit into their lineups at 5. It truly depends on the draft itself. Sometimes you are fortunate enough to draft an Elias Pettersson or Jake Sanderson. At 5, teams seem to either go with the high floor guy or the highest boom-bust guy. However, fans will always expect that draft position to produce a superstar because it’s so high in the draft, despite the fact it rarely does.
In the last 20 years these have been the selections:
Ivan Demidov, David Reinbacher, Cutter Gauthier, Kent Johnson, Jake Sanderson, Alex Turcotte, Barrett Hayton, Elias Pettersson, Olli Juolevi, Noah Hanifin, Michael Dal Colle, Elias Lindholm, Morgan Reilly, Ryan Strome, Nino Niederreiter, Brayden Schenn, Luke Schenn, Karl Alzner, Phil Kessel, Carey Price, and Blake Wheeler
Your odds of getting a top line forward or top pairing D are extremely low at 5.
