Notes from Wayne Winston, part 4
One of the most fascinating aspects of Wayne Winston’s work is the ability of adjusted plus/minus to, in the words of Gregg Popovich, “indicate trends.” My conversations with Wayne Winston have mostly operated at the level of 5-man units. But last night he sent me an email that’s worth posting because of its focus on a single player’s performance in relation to a particular teammate. How well does Player X perform with Player Y?
Winston:
One more tidbit: Mason is great with Manu in and Jefferson out: the Spurs play at +14. The rest of time Mason is in the Spurs play at -2. The +14 level depends little on who else is in [for the Spurs].
Remarkable.
Not only does this spotlight Manu Ginobili’s unique ability as a playmaker, but it gives the Spurs a very good idea of how and when to deploy Mason Jr., who is on the fringes of the rotation. If the Spurs want to optimize their bench, and the minutes of Mason Jr., they’ll only play him in tandem with Manu Ginobili, and without Richard Jefferson.
And not surprisingly, Aaron Barzilai’s APM numbers support the same conclusion. Have a look.
To the extent that APM reveals “secrets,” this is an important one.
