For NBA fans, Lance/Green jump ball last night

[thedewed]

Just curious, what I saw was Lance get the tie up with Green on the ball as Green held it over his head, then Green in trying to protect the ball twisted so that Lance's arms end up around Green's head. One official had jump ball, other had foul on Lance. The jump ball call came before the foul call, and then is the sequence as well, i.e. the ball was tied up, then as Lance kept his hands on the ball Green moved so that Lance's arms looked to be around Green's head.

The question, I know that customarily if there is a foul and jump, the jump prevails, but is that always the case if the jump came first? I would think that the first to occur would prevail?

And of course, if the defender is keeping his hands on the ball and the movement of both ends up with arms into the original ball handler, I don't see that as a foul. We see it more often on a tie up up top, then one player pulls the ball down and pulls the other player over him.
