So KG has a better inside game than Dirk?
How about Rasheed Wallace, how does his lost post game compare to Dirk's and KG's?
The "raw" numbers:
KG: 27% of shots from inside, 72.5% shooting percentage on inside shots (53.9%, .539 eFG% overall)
Rasheed: 15% of shots from inside, 66.4% shooting percentage on inside shots (43.2%, .497 eFG% overall)
Dirk: 19% of shots from inside, 56.5% shooting percentage on inside shots (47.9%, .510 eFG% overall)
None are a true post player, but I'd rank KG as the best low-post option, by a fairly large margin. Dirk is probably the best overall scorer, although he and KG are close.
Two other players:
Big Al: 47% of shots from inside, 64.5% shooting percentage
Gasol (with Grizzlies): 45% of shots from inside, 63.3% shooting percentage
Gasol (with Lakers): 65% of shots from inside, 66.2% shooting percentage
