In a previous article, I looked at the effect of roster consistency on overall team performance. There were enough interesting trends in the data that I wanted to look a little closer and try to see if there is a “right” number of changes that teams should make on a week-to-week basis.

After looking at each squad’s rotation and how it affected their performance over the past three years, it makes sense to look at how changing lineups from one week to the next effected team’s performances in that week. That is to say, given a team’s roster changes from the previous week, how likely were they to perform well?
