I did an offensive list like this in the Buddy Hield thread but here are some stats on our players on the defensive side of the ball. The stats are sorted by type of play. The left side is points per possession given up and the right side is the percentile they're in with respect to the rest of the league. So if you're the 90th percentile, that means that you're better at defending that play than 90% of the players in the league. If you're in the 10th percentile, that means that you're only better at defending that play than 10% of the league.
Take note of small sample sizes and players that aren't really required to defend a particular play all that often. Spot up defense was the highest percentage as far as how often they have to defend that type of play. James, Dedmon and Yogi are all elite but small sample sizes for each because they don't play a lot. Holmes and Bagley are very good at it but they are defending spot up shooters much less than say Ariza would. Hield, Barnes and Fox are all killing us on their spot up defense.
You'd look at the numbers and Barnes is near the top in a lot of them but it's fools gold because he's the best at the plays he defends the least amount. CoJo is rather pedestrian at everything. Are the numbers misleading or are we just noticing the impact plays he makes while ignoring all the random drives he gives up? We do the same thing with Fox. He makes impact plays but is a poor overall defender and it can trick your eye into thinking he's a good defender because you aren't noticing when he gives up points as much as you're noticing when he gets steals and breakaway dunks.
