Wow 10 leagues... no problem. Maybe you can join us next year.
Yeah ELO is interesting for sure. I like that it's simple and just uses points & location.
I've never seen the parity wheel, but yeah it does describe the problem.
Hey I just had an idea. To keep it simple to start just use Avg Points Per Game for offense and Avg Points Per Game allowed for defense. To prevent the infinite recursion we can identify the median 8 teams (25% of the league) on both Offense & Defense from 2015 and give them an average strength rating to start in 2016. Once we fix certain team ratings as average we probably won't have a recursion problem. You can also adjust the initial ratings based on major changes (coaching changes/player acquisition) so that the 8 median teams may not be purely based on 2015. What do you think?
