Regarding Tre not diving. 2 points. First, removing any historical action and assuming you can define the newly created history minus that action is false. If Tre does not dive for that loose ball, we have no idea what happens next. The immediate and long term results are completely unknowable. Immediate: Tre doesn't dive and pulls up short. To do this, he has to slow down, planting one or both feet on floor to stop forward momentum. Cuse kid dives for ball and collides with Tre's lower leg, which is firmly planted on floor. Tre incurs catastrophic knee injury. Long term: Tre is still in game, throws lob to Zion. Zion gets undercut and hits floor hard...
Second point. Tre isn't Westbrook athletically or Steph Curry shooting the ball. Without total hustle, Tre might not be a Duke recruit in the first place. If he still was, he most likely wouldn't be our most important player-without the hustle.
