I decided to calculate overall SRS over 3-year (seasons) windows, for the following reasons:
- • Figured out some time ago how to perform the recursive calculation for SRS like it's done on basketball reference
• Grouping multiple seasons can be used to identify so called team dynasties
• Was inspired by Santserre (viewtopic.php?f=64&t=2012241), details on methodology below*
I included the Strength-of-Schedule (SOS) as well to provide an indication on the competition that was faced during the 3-season window.
Any thoughts? I like how some teams from the late 50's and 60's pop up in the top 15, and it's not all BOS with 66-68 PHI showing up as well. SOS really helps emphasize how tough the competition was LAL 00-02, as one would expect. 08-10 LAL had even tougher competition, relatively speaking.
Edit: Updated the results after correcting the initial calculations. 66-68 PHI drops all the way to 63 now

Here are the results limited to the top 100 "dynasties":

* Similar to Santerre I did the following:
- • Weighed playoff games differently: A single playoff game is the equivalent of 10 regular season games
• Calculated standard deviations above the mean
