Brandsegg-Nygård's PDO (On-Ice Shooting Percentage + On-Ice Save Percentage) is the lowest in the entire league. PDO is a metric that adds a player's on-ice shooting percentage and save percentage while on the ice. In theory, the sum of these percentages should be around 1.00, which is considered normal luck. The Red Wings winger has a PDO of 0.853, one of the worst in recent NHL history.
To put it in perspective, in the last 10 seasons, only one player has had a lower season-long PDO (minimum 100 minutes played): Ryan Winterton last season, with a PDO of 0.850. This shows the magnitude of the bad luck that Brandsegg-Nygård has experienced.
