I believe that it certainly should be more than a minimum number of touches. He's been looking very spry, has the right mindset about battling for early position (a couple of those meaningless tangle-ups and offensive fouls/3 second calls aside) and is actually helping not only the team's defense, but also its offense.
All of this should be encouraged. Few centers can hold him back if he's on a mission to out-run or out-muscle someone for close catches:
That's not to say that I disagree with you, MA. However, it is both on himself AND the team to only get him the best touches. It's still early in the season and thus it's only natural that there have been many possessions where guys don't him with the pass at the right moment. Yet it's on everyone involved that Dwight gets only the best looks.
As annoying as that might be at times, it's still a real thing. Only the 1% -- the Dennis Rodman's and Reggie Evans's -- will hustle without any other reward. We can see that Howard is helping when he's engaged and being involved. The task from here on out is to preserve that energy of his and only improve his offensive involvement.
You definitely want to see less of these far away catches where he takes way too much time. This finish is certainly a stand out, with many of such possessions ending in worse results.
The PPP numbers in post is something I also addressed when tweeting. I saw the same thing. Yet my hunch says that some of his duck-ins and seals simply are under the play type of "cut". He's been very good on those, after all. The clear cut post-ups are the ones on which he has committed turnovers. 0.67 seems way too bad...
That's to say something I probably could have worded in a couple of sentences. More of hitting him when he has low seals in the paint, less of the true one-on-one post-ups. It will do good for everyone.
