I’m using the Colley Matrix iteration process (https://www.colleyrankings.com/method.html)
To summarize, you take the win percentage of every team and correct it against the win percentage of their opponents. Then you have a new win percentage. And I repeat that process until the correction factor is below .001. Essentially this is what I would expect the win percentages to be if the teams played an average team every game.
How is this better than W-L
Imagine two 5-5 teams. One played the Blazers ten times. One played the Celtics ten times. Are those equal teams? Probably not. This accounts for the difference in opponent quality.
