How is that identical? Dinwiddie has 101 ORtg and IW only 85 ORtg, that's 16 pts difference there, total 17 NetRtg swing, that's a big difference.
ORTG and DRTG are tricky statistics for measuring individual production. They more or less just look at how well an entire lineup performs, while making some minor (and somewhat arbitrary) adjustments for individual statistics (rebounds, blocks, steals, etc.). I generally discourage people from using them to assess individual value, especially with this small of a sample size. Something like RAPM runs into similar problems, but it at least tries to control for confounding variables.
That said, I am not saying you are wrong or that these statistics don't have some use in giving a rough snapshot. There's a pretty substantial difference in lineup efficiency with Dinwiddie versus IW, that it is worth investigating further. Just encouraging caution with a highly misused/problematic metric (for individuals - it's fine for team/lineup performance).
Well, I'm not sure the quoted ORTG and DRTG were from Basketball-reference or from NBA.COM, there is difference in their calculation and thus different meanings. And I like the NBA.com one.
NBA.com data pretty much means when the player on the floor, what is the team offensive and defensive rating. Yes, that's a collective number reflecting the line up on the floor, so not a simple individual data. However, if the sample is large enough, it has a good reflection about a player's impact on the team.
That said, for PG, I think this number is more relevant than other positions, as a good PG would make the team's offence much more smooth. Again, for the quoted number, I'm not sure about sample size, but a 85 is quite significantly different from a 101, no matter how you look at it.
Saying those two numbers is identical is just simply wrong.
Well, if you have other argument such as IW is younger, is learning the position, that's okay, but one could not just totally ignore the difference there.
