Shooting is the end state. A lot happens before then. Shooting is a big problem, but just on watching most games, I'd say this
team doesn't get or take nearly enough high percentage shots. And
that's down to their ability to run this motion offense--- which, to me,
relies a lot on high screen and rolls, with cross court motion from the
wings. Their screening is lazy from the big players. The guards don't always take the screen. The big players don't roll hard to the basket or slide off for an open jump shot. The wing players aren't looking to shoot during the open jump shot window. So, it's just listless offensive sets again and again. Sometimes they'll try to change it up by posting or going to the elbow, but that seems to either drain the clock or result in a turnover.
Over the course of the game, you want to get a certain percentage of easy shots / layups / dunks (70% + plus makes), open jump shots or contested low post (40% to 59%), and contested jump shots, late in the shot clock bad shots, highly contested dribble drive (39% and below). Just for very rough, example averages. Carolina is more often than not in the contested jump shot / late in the shot clock bad shot / highly contested dribble drive category. And they are on the low end of the conversion percentage on the open jump shot / contested post shot (if not off any reasonable scale for conversion). They are also prone to turnover spells, which results in zero percent conversion.
You can say they missed a bunch of open shots in this Kentucky game, and they did. Every team will miss open shots. But I'd say, just anecdotally, 70% of their shots must have been bad shots or highly contested.
