Why is this so impossible? Throw the ball up high and instruct the players that it's going up high and to get it on the way down or else you'll rejump it. If it's stolen on the way up, stop play and rejump. If it's thrown up high it will be obvious if it's on the way up or down. In severe and pathetic circumstances,if the tip is stolen twice, whoever steals it on the 3rd try,...TECH.
