MAVS 108, PELS 92

[mvossman]

I could be wrong, but I would bet a lot of money that Kidd thinks that +/- lineup data is in fact reliable and gives useful information that he takes into account as a coach. I cannot imagine any modern coach refusing to look at that data or thinking it doesn't have something to offer. Again, I bet Kidd was protecting his players and also pushing back against knee-jerk interpretations of such numbers. 

One thing I feel like I can be quite certain of: the analytics department guys for the Mavs are not blowing off Luka's +/- numbers so far. I bet they are digging into those numbers trying to make sense of what is going on. Nothing may need to change and things may "correct themselves," but if you care about the team then you don't just watch the Mavs getting outscored by a rate of 10.6 pts when Luka plays and not pause with concern and curiosity.

As Mavslvr pointed out, I think you are looking at +/- data differently than teams generally do.  I don't think they generally look at it to assess an individuals impact on the court, especially over a small sample size.  I think teams are more interested in lineups, and what combinations work and don't work.  There is still a lot of noise in small sample lineup +/- due to who they played against and the general high variance of 3 point shooting on both sides.  I would not be surprised if they use something more advanced that looks at things like open or wide open threes and derives an estimated +/- on small samples.
