I know you like that "in the paint" stat, but it extends out to 13 feet from the front of the rim, so it's not really a great measure for accuracy "away from the rim". I am much more comfortable with Sommerville taking a shot in the paint near the FT line than I ever was with Omoruyi.
So far this year, LS is:
5-5 (100%): Dunks
44-65 (67.7%): At the rim
36-88 (40.9%): Other twos (including too many damn-fool 21 footers)
1-8 (12.5%): Threes
Cliff last year:
51-62 (82.3%): Dunks
102-155 (65.8%): At the rim
27-94 (28.7%): Other twos
1-5 (20.0%): Threes
Cliff the year before:
73-82 (89.0%): Dunks
146-229 (63.8%): At the rim
29-102 (28.4%): Other twos
4-22 (18.2%): Threes
LS is already a more efficient scorer on non-dunks as a freshman than Omoruyi was as a junior or senior. They are two very different players with different styles and different physical attributes. You cannot expect LS to fit into Omoruyi's shoes, nor should you.
Lathan has better post moves than Omoruyi had, with more of an ability to receive passes in the high post and work his defender with his back to the basket. He has better touch on layups and short shots than Omoruyi had. On the flip side, Omoruyi's wingspan, elevation, and overall athleticism allowed him to flush damn near anything he caught close to the rim - which Sommerville doesn't have.
It’s the defense that set Cliff apart quietly. He didn’t allow opponents to score easy baskets in the paint.
Lathan’s defense, in contrast, is extremely poor. He’s not going to simply “get better” at it. It’s his whole style and approach on that end.
