What if he's better than a bottom pairing D? I would not make my entire evaluation based on a couple of charts. They are very finnicky for dmen. You have guys like Ristolainen who we were told was horrible for years and now suddenly the last three years he's good. You have guys who change teams and suddenly have a massive change in results. Let's say Brady Skjei as a quick and obvious example off the top of my head.
I don't know if he's good or bad. I don't see the harm in delaying the pick by a year (since as stated he can be traded later) to find out.
I have still yet to get an answer to the question of "If Soucy is so bad, why does he have the 8th lowest GA60 of the 120 dmen to play 5,000+ minutes since his first full year (6 years). It's not because he was great 5 years ago because he ranked 14/217 just last year (500+ mins). If you can't answer that question then I don't think it's fair to make a strong declarative statement without seeing things through. Yes, Lindgren ranks 12th but I can give you reasons as to why Lindgren would. Playing with Fox. Playing in front of Igor. I think we need to remain skeptical and get more information.
Most of the players in the top 10 there have been considered very strong defenders. Carlo, Spurgeon, Forsling, McDonagh, McAvoy, Heiskanen, DeMelo (fox 11th). Grzelyck and Mikey Anderson are 1-2 which definitely feels a bit weird but Anderson is likely a function of being stuck to Doughty (13th best). Not sure what Grzelcyk's deal is outside of being in Boston since he wasn't always with Boston but the results were great. That said, they are bad this year in Pittsburgh but they've also had atrocious goaltending.
