The shot was much closer to straight on than it was from the wing.
Regardless, there are lucky shots that go in all through the game, and UCLA had plenty go their way.
You only have to rewind the clock, what, 3 seconds? It's not like Juzang planned that miss so that he would get the offensive rebound. Could've easily just been a run-off-the-mill defensive rebound, game over. Instead Juzang ties it and we get a classic buzzer-beater on the other end. I'm not complaining.
