With the season around the one-third mark (time flies, eh?) it's time to update the MLS PDO rankings.
As a reminder, PDO is a combination of a team's shooting and save percentage. It's a useful measure for demonstrating luck.
Teams should have a value within a couple points of 1.0. If a team's value is considerably higher than 1.0 they can be seen as being unusually lucky. Conversely, a team well below 1.0 is having considerable bad luck.
No measure is perfect. There will always be outlier figures and, with PDO, those outliers can likely be explained by a single player having an outstanding string of results. However, even if that's the case, fans should be wary of a high PDO. A correction is likely.
When we last did these rankings Dallas was on top of the league and had an insanely high PDO. Their PDO is still among the highest in the league, but is dropping quickly -- just like its standing. You can't take the points off the board that they gained, but you could have anticipated the fall by looking at the PDO.
The list below the jump.
[PRBREAK][/PRBREAK]
1. RSL 1.09
2. New England 1.05
3. Dallas 1.028
4. New York 1.027
5. DC United 1.023
6. Vancouver 1.021
7. Seattle 1.01
8. Columbus 1.007
9. San Jose 1.005
10. Toronto 1.0
11. Kansas City .998
12. Portland .988
13. Chicago .887
14. Colorado .974
15. Galaxy .973
16. Houston .967
17. Chivas .959
18. Philly .954
19. Montreal .929
Basically anything between .980 and 1.2 can probably be viewed as normal. Those teams are not receiving any more or less luck than they should expect.
Outside of that can probably expect a correction. That's especially the case at the top and bottom of the list.
Montreal is interesting. It's likely a case of the Impact just not finishing and it suggests that Montreal should improve if Di Vaio's form gets hot.
