Richaun Holmes - all he contributes is a contract for trading

Err what? That's on Powell... Green picked up the right guy after what Powell did (or to be more accurate, after Powell didn't do diddly). Powell left the man he was on (Mann), then didn't pick up his Center counterpart either (Zubac). Green had a decision to make and picked the right one... while Powell was off floating in free space.

Speaking of free space, Powell seems to have a lot of it between his ears.

Powell was loading up to help on any Harden drive as designed.  Green's responsibility was to keep a body on Zubac.  The defense was designed to leave Mann open in the corner and scramble out if the ball reached him.
