Ignore all the red for a second (as well as the 53 percent at the rim, which is bad) and just focus on that one plot of green. When Wall shoots mid-range jumpers from the right elbow, he scores more often than he doesn't. When he shoots from straight on, he rarely scores. When he shoots from the left elbow, he almost never scores. When he shoots from the right corner, he also almost never scores.
Why is this? I have my theories and will probably be tracking this on Synergy in the coming days, but I'm curious to hear your thoughts.
