I now realize that Adjusted player pairs and triplets could be found - by this method- by manually sorting and summing the appropriate 5 man lineups. I might try that for a few pairs but if you do a global sort or perhaps add a search function to speed it up that would be cool.

Adjusted player pairs and triplets would be another interesting revelation.

Yeah I have read his work on the topic before, although for some reason (at the time at least) it didn’t seem to do what I was looking for.

I’ll look again. :)

What you’re describing is basically Dan Rosenbaum’s adjusted plus/minus. As for whether there are “enough combinations,” the answer is probably not if all you have is one season’s worth of data.

BasketballValue calculates adjusted plus/minus for the current season here:

And you can find a lot more links on the topic in the “Dan Rosenbaum’s adjusted plus/minus” section here:

This is very interesting work, something I’ve played around with in my head but never tried to actually do anything with it.

That said, the next level in my thinking is: can you isolate player performance based on who they’re playing with and who they’re playing against?

Since you’ve already put the data together, are there enough combinations of say Nash without the “other guys” to determine how much the “other guys” contribute to his performance and vice-versa?

Wow, amazing stuff.

Some observations:
- A lineup with Steve Nash among the top defensive teams? Shawn Marion must have been good.
- It doesn’t seem to be Marbury’s fault that NY sucked so much.
- Nash and Stoudemire really make PHX’s offense tick.
- Denver’s new strategy is trying to beat LAL with one of the worst lineups in the NBA. If they’re indeed an OK defensive team, it is because of Kenyon Martin.

Yeah, there isn’t a team column. I didn’t put it in basically out of laziness - it wasn’t in the original BasketballValue data, and I didn’t feel like writing a formula to insert it. But it wouldn’t take much time, so I’ll try to go back and add it some time soon.

Thanks very much.

For some reason I am not seeing a team column at google spreadsheets or in the csv file.

Will study the file a bit before commenting on the data but clearly this represents a great leap forward beyond the raw 5 man lineup data as you show that the quality of lineups faced varies significantly.
