NBA Vegas SRS Rankings

If you’re familiar with Basketball Reference you’re probably also familiar with SRS. SRS stands for Simple Rating System. It rates teams by taking their point differentials and adjusting for their strength of schedule, then taking those updated rankings and adjusting them repeatedly until a stable rating is found. A detailed explanation of SRS can be found here.

I ran the SRS formula for the 30 NBA teams, but instead of using each team’s actual point differential, I used the point spreads from Las Vegas to rank the teams. The idea is to get a rough picture of what Las Vegas/the betting public thinks of each team. Here are the results:

  1. Miami +7.4
  2. San Antonio +6.2
  3. LA Clippers +5.4
  4. Chicago +4.8
  5. Houston +4.1
  6. Oklahoma City +4.1
  7. Indiana +4.0
  8. Memphis +3.4
  9. Golden State +3.4
  10. Brooklyn +2.9
  11. Minnesota +1.7
  12. New York +1.1
  13. Portland +1.0
  14. New Orleans +1.0
  15. Dallas +0.9
  16. Cleveland -0.6
  17. Detroit -0.7
  18. Denver -0.8
  19. Washington -1.0
  20. Atlanta -1.4
  21. Toronto -1.5
  22. Sacramento -2.0
  23. Milwaukee -4.4
  24. Charlotte -4.7
  25. Phoenix -4.8
  26. Orlando -5.0
  27. Boston -5.4
  28. Utah -5.5
  29. LA Lakers -5.6
  30. Philadelphia -6.6
