This is true, but could be misleading.
At ES, Durzi does have more dzone starts than ozone, but so does every King except Spence, Clarke, and Walker. The Kings aren't really deploying anyone defensively, among the regulars Ozone start % is pretty consistent sans Walker and Clarke.
His PP time is 2:35 per game, Doughty's is 3:16. No other defenseman is even close. There are only 29 defensmen in the league who average over 3 minutes per game. Durzi is 38th overall in PP ice time per game in the NHL, that's major opportunity.
I just don't see how he gets 50 points if he's deployed on the 3rd line. He gets a lot of points on the PP, but he also has the highest points per 60 on the team at ES. Based on his pace 4 minutes less per game means 8 points less per season at ES. Other factors will play into that obviously, but everything points to him being between 38-42 points if deployed in a 3rd line role.
One thing will improve if he moves down, and that's goals against. He has the worst GF% on the team, even worse than Walker.
Sifting through that data did tell me one thing for certain, that's unrelated, but Mikey Anderson is a f***ing stud.
