So, I'm going through NBA.com's advanced stats and accumulating data, and I notice defense vs isolation, you have players like Middleton, Dudley, and Bazemore giving up .94, .91, and 1.05 PPP respectively, while you have notorious defenders like Harden, Melo, and Pau giving up .73, .71, and .65 PPP respectively. I recognize that this is only one aspect to defense, but why are there discrepancies, like this, when it's obvious that the Middletons and Bazemores of the NBA are a lot better defensively, according to the eye test than the Hardens, Melos, and Paus? Is it because those guys are guarding some of the elite players of the league, while other teams will too frequently attempt to exploit whenever a player has Harden/Melo/Pau on them? |

because you don't even know exactly the question you're asking. are you asking who is the better defender? [part 1] and why are the worse defenders showing higher PPP numbers? [part 2]
they are two separate questions. sounds like you are mixing the two. |

Often it has to do with how teams defend iso. _________________ “We must always take sides. Neutrality helps the oppressor, never the victim. Silence encourages the tormentor, never the tormented.” ― Elie Wiesel |

I don't know much about these particular data, but off the top of my head the reasons could be:
1. Different team styles
2. Different positions
3. More difficult assignments, as you note
4. One season provides insufficient data
5. Guys who are weak/strong in isolation have different strengths/weaknesses in other elements of defense
6. The level of data available to fans on nba.com isn't sophisticated enough to really capture the true situation
7. The "eye test" is wrong.
That's complete off-the-top-of-my-head thinking and you'd need to get input from someone who really understands this particular data
Interesting question, though |
