You highlighted that rule, but you didn't acutally read it. The contact with the rim needs to cause an unnatural bounce. Which it clearly didn't in real time or the replay. Lee just whips it off the backboard with no chance of it ever falling into the hoop. In fact it is the referees job to determine angles and to decide whether or not that ball would have gone in without the minor contact that gasol made with the rim.
it is a ref's job to judge wether a ball that has not yet made contact with the rim or backboard had a legit chance to go in, or if it was going to be an airball that falls 5 feet short like, say, derrick whittenburg's shot... or if a ball is thrown like a rocket off the backboard.
lee's shot hit the backboard and hit the rim... therefore it is a shot that has a chance, and it clearly should have been called goaltending.
if a player hits the rim while the ball is still on the backboard or on the cylinder, it's goaltending. period.
yes, howard, too, got away with goaltending earlier in the game. but to try and claim that pao didn't committ goaltending on lee's shot is silly. he did, he got away with it.
did it cost orlando the game? yes and no. immediately yes... in the grand scheme of things, no... like was already brought up howard got away with a goal tending earlier in the game. also orlando still had overtime to try and win, and thirdly lee should have made the shot regardless.
but yes, it was 100% goaltending.
