Quinn Hughes = do not want. His offensive gifts are offset by his defensive deficiencies.
I'd expect Perunovich to be very similar, and to ultimately get crucified like Shattenkirk was.
Quinn Hughes being utilized the way Vancouver did last year is an organizational failure. He inexplicably played over a minute a night more than any other Canuck defenseman at even strength and got about 85% of those minutes with Travis Hamonic. Making that tandem your most-used even strength pairing is...something else. Put another way, those 2 got 13:42 a night together at 5 on 5, which was
3 minutes a night more than the next-most used pairing of Schmidt/Edler. The way Vancouver used Hughes might be the biggest misuse of a player in the NHL last year.
With that said, if your organization just doesn't want Quinn Hughes then that is as big of an organizational failure. He's a top 5-10 PP QB in the league and a top 40 offensive driver at even strength. That's enormously valuable and any GM who can't build a successful blueline around that shouldn't be in the league (I'm a firm believer that Jim Benning shouldn't be an NHL GM).
Not every defensive prospect needs to be a shut down D man or a Norris caliber 2 way guy to become highly valuable as a fully formed player. There is a very, very good chance that we don't have any prospects who will top out as greater than an elite PP QB who needs to be heavily sheltered at even strength in the bottom 4.
This revisionist history regarding the crucifixion of Kevin Shattenkirk is getting tiresome. Shattenkirk became expendable to this franchise only when a 23 year old Parayko actualized into a legit top 20 RHD and Petro had 4 more years left on his contract. He was a career +24 as a Blue averaging over 21 minutes a night in his career here. He posted insanely good possession stats over his career in St. Louis and was the 3rd most used D man during the playoffs during our run to the Conference Final. The Blues were 3rd in the NHL in goals against per game during Shatty's tenure as a Blue and Shatty played more even strength minutes in that stretch than any skater besides Petro. Clearly, you can build a successful blue line with a player like him logging significant time.
For Colorado, he was half of a trade that returned a 22 year old 1st overall pick, a bottom 6 center and upgraded their 2nd round pick to a 1st round pick. For the Blues, he returned a 1st round pick and a young middle 6 forward (Sanford) as a pure rental. We would have gotten another 2nd rounder if Washington had re-signed him or made the Conference Final. As a UFA, he reportedly took a pretty big discount to go to the Rangers and "only" got $6.65M a year for 4 years. That worked terribly, he got bought out and then the Lightning brought him in as their #5 D man. He had 34 points through 70 games playing 19 minutes a night, then had 13 points in 25 playoff games playing 19:30 a night in the playoffs. They won the Cup with him as their 6th leading scorer in the playoffs. His +8 was 6th on the team. Terrible-player-Shattenkirk still had such an atrocious reputation and value league-wide that he could only find a job paying him $3.9M a year for 3 years in his 30s. He also represented the USA at the 2014 Olympics.
Some people feel that Shatty is a useless, terrible D man. The league as a whole completely disagrees and Tampa had him play a pretty sizeable role in Stanley Cup victory. I will not be at all surprised if none of our prospects are ever as good as Shattenkirk. He is not the example of a poor D man that you think he is. Those types of D men are often paid too much and it is difficult to build the proper group around them if you pay them like legit top pair D men. But that doesn't mean that we should write off prospects as red flags because they might be good enough that they command an overpayment 5 years down the line. That means you use them as cheap sheltered scoring talent through their ELC, bridge them to a cheap/reasonable 2nd contract to keep playing that role and then flip them for assets instead of giving them the UFA overpayment.
