Kuminga's decision-making evolution is exactly what championship teams need. He's doing the opposite of his natural instincts - passing instead of forcing shots - and it's opening up everything for Golden State.
This kind of mid-career transformation is rare. Most players get set in their ways by year 4, but Kuminga is rewiring his entire approach. Compare that to Westbrook who never adapted, versus Harden who constantly evolved his game.
The Warriors desperately need his athleticism because they've been looking old lately. If this version of Kuminga sticks around, it completely changes their ceiling in the West.
