APAG is spot on here. Regardless on who was originally on Lillard the set up of the play screamed "Lillard to the top of the key" ...
I thought it actually made sense to switch Parsons/Beverly because as Lillard came around to the top, Beverly could overplay Lillard to the high side while Parsons continued to trail for any play away from the action.
Not switching on that play is RomarFS.
Moreover, what is amazing to me on a play like that is that there really are only 5 spots where a shot can be taken from given that setup: 1) near corner, 2) top of the key, 3) cross court wing, 4) cross court corner, and 5) entry into the post. If you angle the defender guarding the inbounds between the inbounder and the basket, you take away the near wing and basically anything going to the free throw line.
If you play that shitty of defense in that situation, you deserve your season to lose.
And I hate James Harden ... he acts like such a little bitch on the court.
