http://fivethirtyeight.com/interactives/the-complete-history-of-every-nba-team-by-elo/#rockets How do you rate an NBA team across decades of play? One method is Elo, a simple measure of strength based on game-by-game results. We calculated Elo ratings for every NBA (and ABA) franchise after every game in league history — over 60,000 ratings in total.
ELO----EQUIVALENT RECORD---TEAM DESCRIPTION 1800---67-15---All-time great 1700---60-22---Title contender 1600---51-31---Playoff bound 2014-2015 team: 1650 '08-09 -- 1654
For some reason, I now want to go play chess ... Thanks for the link, btw. Really interesting stuff. I think ELO was also used for the BCS rankings somehow, too.
