After digging into the equation, I think DRAYMOND is pretty good. I like that it's a new way to try to measure defense. The more ways, the better, tbh, since there will never be a perfect way to measure it. I already like it better than DBPM because nothing can be worse than trying to pretend defense can be measured using steals and blocks. DRAYMOND reminds me of defensive WAR stats in baseball and that's a good thing.
The thing I don't like about it is that obviously there was some juggling with the equation to force Draymond Green to rise to the top of the heap. The most obvious one is not only counting the playoffs but also tilting it so that playoff defensive plays are worth significantly more. That was 100% done to get Green to the top spot.
(That kinda reminds me of PER. When Hollinger and company were first formulating PER, they were annoyed because David Robinson would always grade out as the best player of all-time. No matter what they did, Robinson was the best ever. To force Michael Jordan to the top spot, they had to bolster BS stats like missed field goal attempts. Only then was Robinson dethroned
