I heard the way the announcers explained what the goal tending rule is. That touching it has to interfere with the ball, etc. The thing is though, that rule needs further review. In this case, if Gasol isnt allowed to come into contact with the rim then he has to play either much more conservatively in relation to how high up he goes or he has to play a little farther away from the rim in order to be sure he doesnt ocme in contact with it. Either way it makes the shot easier for the offense and in this case it may have made the difference.
