Not sure I can agree on that. Don't get me wrong that there's going to be huge changes from Hlinka to June 2019, big ones including players who will fall like Veleno did after being considered a top 5 pick. However, if Broberg played like he did in Hlinka throughout the season I would absolutely take him in the top 5 and no questions asked. Big, smart, and very mobile left-handed defenceman hard to ask for anything else.
While if Avs pick 15th again with their draft pick, a player who can have a major coming out party this year is Nicholas Robertson at eliteprospects.com . Probably grows to 5'11" when everything is said and done, but his shot tormented goalers in the tourney - reminds me of Phil Kessel.
Left handed defenders are busts. Just look at Hanifin, Murray, and Zadorov.
