More tracking data on stats.NBA.com

Post by AcrossTheCourt »

Check out the new layout and the new tabs on player pages among other things. You can now look at every single shot with an amazing array of attached data like shot clock and how close a defender was and who it was, more rebound info, pass info, and defense too.

I have a question about defense though. Here's an example:
http://stats.nba.com/player/#!/101106/tracking/defense/

DFG% is the field goal percentage of the guys Bogut is defending. Clear enough. FG% is the usual FG% of the guy who's being defended ... but what's usual? Is it based on location, single season data, what? For example, his overall net difference is -4.8. But his 2PT net difference is -5.9. But the ratio of two-point shots defended to three-point shots is like 15 to 1. Shouldn't the net difference be closer to -5.9?

Or is the usual FG% calculated based on the category? So if a guy shoots 50% overall, then what's what you use in the overall category. It doesn't matter if he shoots 60% inside and that's the only shot you defend him against.

Have to select 2013-4 to see the data you intended to reference.

Just starting to understand all this.


"Shouldn't the net difference be closer to -5.9?" I think the math checks out. the lines add up into the top line total.

"what's usual? Is it based on location, single season data, what?" Depends what you select on the dashboard. They could perhaps add by traditional positions though.

"Or is the usual FG% calculated based on the category?" I think so.
