It's iffy because they ended up with higher %'s than were logically possible considering his overall 2pt%. So either they used a non-representative sample or they were fudging the #'s.
The issue was that MJ took more shots at the rim than at close range during the first part of his career.... but he was also a 52-53% shooter on two-pointers that entire time. So he CAN'T have great #'s at the rim and at midrange both, it's not logically possible. If he was a 70% guy at the rim back then then he'd have to be shooting around 30% from midrange for the math to work.
We don't have numbers for him until 1997, and by that point he was shooting way more midrange than at the rim. And the sample size is small so the #'s are weird. In '97 he was shooting 52% at the rim, which is fukking horrible, but 51% at midrange which is top level elite. In 1998, he was 64% at the rim, which is solid, but fell to 44% from midrange, which is very good but not elite anymore. So which is it? Even in his 2nd stretch, we don't know whether he was at the top of midrange or just very good, we don't know if he was pretty good at the rim or struggled.
