Taking Dancan out of the game with more than 3 minutes remaining in the 3rd when both Amare and Shaq were in foul trouble tells me that Pop didn't mind losing this one.
CIA Pop might have had a different plan.
When Shaq started rolling in the beginning of the 4th, there was no double team on him. Remember that both Amare and Nash were on the bench. Yet the Spurs gave O'Neal jump hook over and over again. I believe Pop "deliberately" didn't put Kurt Thomas on Shaq.
Why?
One, he didn't think winning this game would really matter (He gave in in the 3rd).
Two, he didn't want to expose the Spurs's real playoff strategies (no double team on Shaq, no Kurt Thomas in the second half).
They will come back with vengeance two weeks later.....
Go! Spurs Go!
