I'd like to see such a workup, too. There are a few other aspects of 3 pt shooting I'd like to see treated as well. For example, by using the player tracking system they should be able to give shooter's percentages when the shots are contested vs wide open or, maybe even, contested, closely contested and uncontested. There may be some value of a breakdown by where in the shot clock they occur - giving D'Antoni some credit he seemed to be the first one that espoused the idea of shooting threes in transition because you were more likely to be unguarded then. As aspect that interests me is how well guys shoot them in the playoffs vs the regular season. You expect somewhat better D in the post season but its still important because its a losing idea to set up your offense for the case of the reg. season if you can't carry it over to the playoffs. (I noticed this year that Bonner got much less PT in the playoffs than he did in the regular season - and Bonner's defensive stats are not bad. I guess we all know Pops is a master at adjusting.)
The player tracking data could give us much more complete data on individuals' defense all over the floor instead of just at the rim but I guess that's another story.
