Here are the stats on different types of offensive plays our bigs make. I ordered them by the relative frequency by which they are used by our bigs:
Pick'n'Roll:
The frequency on P'n'R of our bigs are relatively close. The result - Gobert is best in the pick and roll, followed by Favors(both are above average as a roll man in the pick and roll), then Booker at 31.7 percentile and Enes at 20.2 percentile. That means that out of all players in the NBA Enes is worse than 80% of the players in one of the most used offensive vehicles in the NBA.
Cuts:
Both Derrick and Enes are above average on those for the league, with Derrick being slightly better. Rudy is at about average and Booker is kind of bad at them.
Post ups:
Interestingly enough, here Booker scores higher than everybody at 88 percentile in the league, followed by Enes who is above average and uses 15.8% of his possessions on postups. Derrick uses 22% of his at below average rate(32 percentile), which is pretty bad. If I were the coaching staff I'd try to avoid those situations or pick up spots and specific match ups. Rudy is horrible at post-ups, but smart enough not to use many possessions (only 5.7%) on them.
Putbacks:
Rudy uses whopping 31% of his possessions on putbacks and finishes with amazing efficiency(85 percentile). Booker is even better(efficiency-wise) and is one of the best on those in the league... whenever he reaches the ball he finishes it. All our bigs are pretty good at those and are well above average for the league.
Spotups:
Spot-up... yep! The category where Enes was supposed to be our best big. Guess what. He's the worst - 13 percentile... He's worse than 87% of the players in the league and uses 17% of his possessions at those. Rudy doesn't spot up. All our bigs are below average spot up shooters.
Transition:
Favors and Gobert are elite at finishing in transition at about 95-96 percentile. Booker and Kanter are both great, too.
Isolation:
This is probably the most inconsequential category, since our bigs isolate very rarely. Derrick is surprisingly the best at it and is better than average for the league... Both Enes and Booker are below average.
So what does this tell us? Is Kanter this overwhelming offensive force that we've gotten used to thinking he is? Pretty much the only category where you can make an argument that he's overwhelmingly better than Favors is in post-ups. Favors is better in the pick and roll, in transition, in spot-ups and in isolations. They are pretty close in cuts to the basket and putbacks. All this is reflected in their TS% and eFG%, where Enes is the worst out of all our bigs.
Now I won't say Booker or Gobert are better offensive players since the usage is not equivalent and since I know that if given those possessions that Kanter uses, their efficiency will probably get down, but I am fairly comfortable in saying that right now Favors is better offensive player than Kanter. They use comparable number of possessions and Favors uses his in a much better and smarter way. If they work around the post-ups and give him less of them in favor of other more efficient options, he'd be an absolute beast.
