There should have been a Doc vs Green moment after the last play. I just watched the clip several times and Green was in perfect position for that rebound and he never even came out of his crouch position or raised his arms up. I have no clue what he could have been thinking. If you are under the rim and the ball is coming down, you try to get the ball. Little kids understand that but Jeff Green does not.
I watched the replay, and it looked to me like Green was working to keep Ryan Anderson from being in position to get a rebound. I think that play was on KG—yes, he came over to help on Gordon, but he was still in good rebounding position, and all he had to do was put a body on Davis, or go up and grab the ball himself, and he didn't do either.
I've watched the replay several times now:

Remember, the goal in that situation isn't necessarily to 'grab the rebound' - they only needed to prevent a put back.
KG actually did the right moves in the sequence - because Gordon beat Bradley to the right side and drove the paint, KG had to release from Davis (who he'd had blocked at the left elbow) to help contest the shot.
What was supposed to happen when KG released is that Lee, who was standing just outside the paint on the left, should have rotated in to block Davis from crashing.
Three things made this play work:
1) Roberts swung out the the right corner forcing Pierce to setup a full step out from the paint, vacating the right side of the paint. Nothing done wrong by Paul there, it is what it is.
2) Given that, Bradley needed to force Gordon to go to his left, to the overloaded side. You HAVE to show him the left side and overplay the right in that situation. Instead, he tried to square him up and Gordon beat him to his favorite side with the spin move. Once Gordon penetrated, KG had to collapse.
3) Lee forgot to rotate. Davis was able to crash and tip it.
A lot of folks are screaming at KG as if this play was his fault. But the two basic mistakes in the team defense were by Bradley and Lee.
