You can actually look at where Herb (or any other player) took all of their shots precisely on the court - at least as precisely as publicly available NBA tracking data allows - on nbashotcharts.com
It's in the Raw Shots section, you can type in any player and search by year, by date, and by quarter/half if you want to.
If you look up Herb last season he shot 43/151 from the midrange and almost all of them were those long-midrange 16 footers and out. He barely took anything closer than about 15 feet that wasn't right in the paint. No 12 footers from Herb. 43/151 is bad, by the way, not good at all. The good news is, that's the smallest percentage of shots he took in any zone. This is good because unless they're astronomically elite, you usually don't want roleplayers taking middies anyway. 46% of his shots came at the rim, where he produced 1.32 points per shot, which is actually pretty damn good. 29% of his shots came from 3, where he was 1.03 points per shot; not great but solid enough.
From midrange? 0.57 points per shot. Please do not take those anymore. Compare him to a true mid-range maestro like CP3 (1.13 points per shot) or Durant (1.06 pps) and it's clear why you don't want him taking those.
