Shows you how little value stats like PDO actually have
Good teams generally have a positive PDO and bad teams a negative PDO and there is a correlation between that team's PDO and their shot differential/scoring differential/xGF etc. unless you are a team that lives or dies on extreme shooting% + hot goaltending (like the Jets for example). Thats a risky way to conduct business though. If Helle goes down, the Jets are up a certain creek without a paddle IMO.
Seeing where the Leafs rank the previous 3 seasons have them 8th in the league:
1. Tampa
2. Islanders
3. Jets
4. Penguins
5. Caps
6. Avs
7. Bruins
8. Leafs (1.009)
5 of the 8 are also in the top 10 for xGF% with the Jets being only real outlier.
What do the bottom 8 teams for PDO look like?
24. Sens
25. Habs
26. Ducks
27. Sharks
28. Sabres
29. Devils
30. Kings
31. Wings
That all makes sense though right? Team with good shooters and good goalies will tend to do better and it gets amplified greatly if they outplay opponents.
So the Leafs had a PDO of 1.009 the previous 3 years as well as an xGF% ranking of 3rd best in the league showing that they were a good team that wasnt lucky in doing it.
The Leafs started the year 2-4-1 but were they really playing badly? If they had poor underlying stats to match a low PDO then the answer would be yes but lets check it out.
Leafs PDO: .947
Leafs xGF% ranking: 54.16 (9th in the NHL)
Not only was the Leafs PDO waaaaaay lower than their previous average with the same core but they were also largely controlling play which should scream out to anyone they were getting very unlucky the first few games (hell the eye test was saying that).
Since then things have regulated (as anyone with half a brain would have predicted) and the current rankings stand at:
Record: 9-5-1
PDO .991
xGF%: 56.15 (2nd in the NHL)
The Leafs have actually been playing so well this year, they probably should have a record more in line with 11-3-1 (Rangers and Sharks games come to mind for bad bounces) but it's nice to see things regulate sooner rather than later as I couldnt take some of the more active posters embarrassing themselves much longer.
Does PDO have value? It's literally the stat that was predicting the big correction coming up. The Leafs are one of the best, most consistent, hardest-working teams in hockey. Of course they were going to go on a run.
