Zamula I doubt, right now he's a very long shot. If he improves, if he fills out without slowing down, if . . . check him out in two years.
Hogberg will not only beat out Hagg, he may even beat out Sanheim, starting on the 1st pair on the best team in the SHL at 20 with great possession numbers, he's not going to be flashy, but there's something to be said for reliable defensive defensemen. Sanheim has great promise, but at least reading Appleyard, Hogberg has the hockey IQ and consistency to be a more reliable top four defenseman.
Klaynuk is a wild card, he could be a college flash in the pan or a Ghost like steal later in the draft. We'll see when he hits the AHL.
Friedman has progressed steadily, but I don't see anything that stands out yet, so I can't project him over Hagg at this time.
I think Hagg's real competition is Morin and eventually Ginning.
I doubt with Provorov, Sanheim, Kalynuk that they'll carry more than one big LHD.
And Hagg on the right side isn't as natural as Myers, Friedman or Gudas (if they keep him), and will have St Ivany and Wylie knocking on the door in a couple years.
