People saying he should have planned better, or just stay and play the game, well can't really say with out being kicked, but he was on the Spurs not making the playoffs, plus some times things happen no matter how many "precautions" you take.
Sounds like they were going to educe between games 2 and 3, so they had a plan, but nature don't care about your plans.
Family takes first priority every single time. What if some thing happens during birth and the kid only lives a few hours and you chose to play a game instead of being there with your wife and holding your kids hand in their last moments, or you wife, you never know.
