After downloading the pics and zooming in, I got a better chance to see what they're saying.
I wanted to test the hypothesis that Ginobili was the Spurs' best corner three shooter, so I did a couple of quick chi-square tests. The results I got suggests that Ginobili hasn't taken enough attempts to say he's for sure a better corner three shooter than either Leonard or Green. Ginobili had only taken 36 corner threes as of that picture. Green had taken 128 (and Leonard 92).
But I get that should want to show that Green is a significantly better three-point shooter than Ginobili is. Doing a chi-square test on that, I found that Green has had significantly more success shooting from three this year (total attempts) than Ginobill. Incidentally enough, there was no significant difference between either Leonard and Green or Leonard and Ginobili.
To me, this data reinforces the idea that Green is more than the run-of-the-mill, D-and-corner-three player that the Spurs have employed as their starting two-guard for much of the Ginobili era. He shot the best out of the three players from non-corner three spots. That already makes him a more dynamic weapon than people typically give him credit for. It's one thing to be able to run Green off corner shots; it's another to have to run him off shots at the wing, where the recovery distance is longer.
