Does the game crash right after you finish the game? And if so, does the save file corrupt?
Did you try placing your My Player on the 60 day DL and simming the day your player is scheduled to play?
2K Sports didn't seem to test the playoffs much in this game. The third season has corruption problems as well (except it crashes to the desktop when you save at the bracket and won't let you load again, if you play the game it crashes and corrupts the save file).
Hopefully the patch will fix the crashing and corrupting.
