This is officially the third version of the DPI. From its beginning, I threw in what I think the most important stats are, put it all together, and came out with a singular value on the other end.
In the beginning I would add up all their rankings and divide that total number by the amounts of stats. The problem with that, all rankings were treated equally. So, if you had the 275th best 2-pt% defense, that could derail an otherwise great team.
Now I was a liberal arts major, spreadsheets are not my friend. However, I have friends who know a concerning amount about spreadsheets.
