The NBA has no interest in a midrange shot. They want to see he can make a wide open corner 3 and shoot free throws.
But the biggest thing is that with TSJ's departure you assume he'll be getting the toughest defensive assignment every night, against a variety of different player types.
Show excellence and versatility there, make great decisions with the basketball, continue being a chaos agent, and look non-catastrophic when shooting it and the NBA will start seeing echoes of Alex Caruso or Draymond Green.
I wouldn't say he's followed an NBA trajectory to this point, but we all see there's more that might be unlocked there. If he's Da'Monte Williams the next two years, great. If he breaks through beyond that, look out.
