As rough as they were letting them play, I don't have a problem with the no call on Ginobili's drive. Was it probably a foul? Probably, but he did get an awful lot of ball, not much different than when Green stripped LBJ a few minutes before that. They were letting them play, so the no call was probably in line with the way the game had been called.
SA's biggest problem, even given all the stuff listed above, was that they didn't stick to the plan on defending LBJ. Too many times early in the 4th quarter LBJ easily got into the lane. The plan was to sag and force jumpers, or contested shots in the paint. They didn't defend him very well for about the first 7-8 minutes of Q4.
