Yes but that's double dribble!
NEW SIM RESEARCH: Humanoid learns basketball skills!
Called Learning to Ball, it involves a physics-simulated humanoid character that plays basketball inside IsaacGym.
It trains seven primitive skills (dribble, gather, shoot, pass, catch, rebound, and a combined defend/locomotion) via adversarial imitation, then composes them into long-horizon plays.
It replaces hard skill-chaining and one-hot mixture-of-experts, which break when subtask policies share few states.
The interesting core of this project is the soft router, blending all primitives every timestep rather than switching to one.
Turning off the high-level router drops shooting accuracy significantly, and it beats a one-hot hard router precisely on the ill-defined in-between states where a switch would stutter. Continuous weighting keeps transitions smooth through states that do not belong to a single primitive.

John Urschel btw
John Urschel just showed that the growth factor for Gaussian elimination with partial pivoting is ~n^{1/2} with high probability, resolving a long-standing conjecture of Nick Trefethen! arxiv.org/abs/2610.06785

One trend that stood out in the SuperCups: forwards as rim runners in transition.
Jantunen. Kraag. Abalde.
Running the middle and flowing into the ball screen — a role traditionally reserved for the 5.

Contrast how Iisalo teaches and emphasizes the hook pass, with how most were taught passing growing up.
This is an example of an area with a big technical gap in coaching. He teaches gaining an advantage PLUS being on target on time; you can have BOTH.
‘Thumbs out’
‘Always pass with two hands’
‘Square to your target’
🛑
Steve Nash/D’Antoni played such a critical role in this paradigm shift - being able to pass with both hands while simulataneously manipulating the defense with your eyes.
Encourage creativity, encourage passing with both hands, encourage no looks.
