I’ll start. Lowest IQ, Jordan Poole. He constantly takes horrible shots. Has bad clock awareness. Constantly over dribbling resulting in him slipping and falling on the floor.
Highest IQ, Lebron James. Anyone with basketball knowledge should already know this. He is a basketball savant. A prolific passer. See’s the whole floor and gets everyone involved. And he’s done this for over 20 years!
Ja Morant has pretty low IQ, not sure if he’s the lowest. Especially in the playoffs, when he’s injured and comes back and still trying to jump over people again.
