Network analysis applied to basketball offense

The price of anarchy in basketball Brian Skinner (Submitted on 12 Aug 2009)

Optimizing the performance of a basketball offense may be viewed as a network problem, wherein each play represents a "pathway" through which the ball and players may move from origin (the in-bounds pass) to goal (the basket). Effective field goal percentages from the resulting shot attempts can be used to characterize the efficiency of each pathway. Inspired by recent discussions of the "price of anarchy" in traffic networks, this paper makes a formal analogy between a basketball offense and a simplified traffic network. The analysis suggests that there may be a significant difference between taking the highest-percentage shot each time down the court and playing the most efficient possible game.

Damn, that Brian Skinner dude is mighty smart. Maybe that’s why Popovich has been emulating the guy.

Dear ptruser,

This has nothing to do with anything, but long ago when I first read your name, in my mind I said it “PT ruser,” (pronounced “pee-tee ROO-zer.” It took me a while to figure out it was “PTR user.”

LOL, I still hadn’t figured that out, until you said something. Good names are like wine, and Spurs, they get better with time.

haha, i used to think alamobro was pronounced like alambre (a laam BRE) but then as i was eating some alambre at guajillo’s i realized it was Alamo Bro. Maybe, just as we have a mapping PTR post, there should be a username pronounciation post, ha

Oh my! That is enlightening! So that’s what “alamobro” means! We learn new things everyday.

Mine is pronounced: Blaze E

the “ase” is pronounced aze like in phase. It is not the word blasé as in non-chalant, laid back, relaxed, unmoved, unconcerned, or carefree. I’d have to think if those apply or not…..

“Theo” is NOT my first name.

Mine combines “cap” and “hill” to be pronounced together as CapHill. Hope that clears everything up.

Mine’s pronounced “Jay Are Double Ewe” and it stands for — oh, never mind.

Seriously, your genius continues to amaze me! And since my “U” key is sticking, it was more difficult than you’d think to type this.

This is, to me, the crux of the article
In such a scenario Allen would have a TS% of 0.625, far above the rest of his teammates who are shooting with a TS% of 0.5. It would seem to be obvious that Ray Allen should be getting more shots than his teammates. But the result of limiting Allen’s shots, and thereby keeping the defense from focusing too intently on him, pays off. In this case it improves the team’s TS% by 2.5%. For reference, in the 2008-2009 NBA season the standard deviation among teams in TS% was only 1.6%, so a difference of 2.5% may be quite significant. To achieve it, the team just needs to consciously choose not to feed the ball to Ray Allen on ∼ 80% of possessions, even when he is their best option.

Substitute Manu for Allen in the above, and Pop’s play calling makes much more sense than otherwise, eh?

Very interesting. By the way, my name is pronounced GEE-no TWEN-tee. Gino is short for Ginobili. Just thought I’d put everyone’s mind at ease.

I feel much better about it now. Thanks.
