My two cents on the only players I know:
Quinn Schmiemann - Left Defense: 6th Round Pick of the Lightning (2019) - went to Flyers camp in 2021.
Lead the Western Conference finalist Blazers in offensive production from the blueline last season at just shy of a point a game playing shutdown paring minutes largely with partner Ethan Brandwood (undrafted - Dallas camp). Quinn's strength is his silence. No flash. No egregious mistake. Consistent. Steady distributor of puck, possessional solid, capable skater (but not as impressive as Lindgren). Hard on the puck but not a masher. He's just always there.
Young for his draft class. The article below stated that in the 2019 Draft (his draft year) that he was ranked as the 13th best defensive prospect in the year using "Corsica's prospect model" which accounts for age, scoring, and league played in. Couldn't find a link. But, last season - having Schmiemann and Lindgren on two pairs, the two ate minutes and just played a settled game.
If he hits the NHL and I think it is possible - he's a 3rd pairing LD who you have confidence with but won't notice. And, there's a role there. Expect he isn't really deficient anywhere but has to improve a bit everywhere.

Viktor Persson - Right Shooting Defense but I recall him predominantly on the left side as once Stacha was out with injury, there were only two left-shooting blueliners on the team: 7th Round Pick of the Canucks (2020).
Half a point per game. Improved over the season as time went on after coming over to get a taste of the smaller ice. Had a bit of a slower start and appeared to trend up towards the end of the season and made significant strides in the playoffs. A team guy - got the sense really wanted to be here in Canada.
Has above-average skating, not afraid of contact, his desire to put pressure up ice can get him into positional issues. He's got skills.
But, he also has a major deficiency - he is inconsistent especially with his break-out passing. He can have a game where his up-ice passing has you smiling with every play he makes. He will then have a game where it feels as though every puck is off his hands to the opposing team.
Until the end of the Giants series/Thunderbirds series, he was rotating through all parings and largely taking 3rd pairing minutes (behind Schmiemann/Brandwood and Lindgren/(Bairos, Hammell) and I was not impressed as Hammell (16 year old) often was out-playing him). But, the last 10 games, he found his game and I thought might have a shot. Didn't get a sniff on the PP but did get some PK time.
I'm not bullish on Persson making it as he comes in as a 19 year old who was 3rd on the depth chart in junior, although playing on his off-side and his deficiency made him sometimes a liability.
