block = jump ball?

Since player control is defined as holding or dribbling a live ball inbounds, if both players are holding the ball then both have control. That is why it is called a held ball!

But if one player is holding the ball and an opponent simply puts a hand on the ball, only the first player has control.

What is the difference in the two cases above?In the 2nd. case,if the opponent puts his hand on the ball,and(in the official's opinion) the player with the ball then can't do anything with it,why isn't this joint possession also?Both players are holding the ball.The only difference is that one of them is only holding it with one hand,but that one hand still fits within the rulebook definition of player control.Doesn't the same reasoning apply as in the first case?

It's not a tough rule to call.It's a jump ball if players from different teams have player possession at the same time,so that neither player can do anything with it.It's just the official's judgement if that tenet applies.
