I'd been playing NBA 2K12 for a while now and had finally gotten to the Playoff finals of my first year. The score was 3-0 and we needed one more win for a sweep. After playing winning the match, the game crashed. I tried again, and it crashed once again. After 56 wasted minutes that counted for nothing at all, I decided to see what I could do.
The fix is simple. Before you start the game turn autosave off. The game should not crash anymore and if you win, you'll be able to go to the post-game conference.
This thread is just for someone on this forum that has the same problem and needs some help or just a lurker that came across this from a search engine. Either way, I hope it helps and saves you some valuable time.
