Remember, these offensive rankings are based on each offense’s Process+ so far this year and how we project their lineups moving forward. It means you’re going to see a little different offensive rankings than you may see elsewhere, and there will always be some surprises. This is based on skills, not purely results! If you have questions about these offense rankings, reach out to Kyle Bland (@blandalytics).
