In a nutshell, PDO is a number when you add Even Strength SV% and Even Strength Shot%. You can do this for individuals, but it also works for teams as well. If a team has a PDO number above 100, that means they've gotten lucky. Anything under 100 is usually a result of bad luck. If you notice this chart, you'll see that the Devils are near the bottom of the league. Meaning the Devils are in actuality better than what they've shown.
