Actually jumping makes the game based on an athletic action, rather than just which way an arrow is pointing, that's more random, which means you want the ODD way of doing things. If you're down 1 with 10 seconds left and there's a tie up, and the arrow is against you, you likely lose, but if there's an actual jump ball, the game suddenly become MORE interesting, not less. Ridiculous randomness is an arrow, which way that stupid arrow is pointing decides the game sometimes, takes it out of the players hands, modern people are IDIOTS "worried" that the refs toss of the ball might not be perfect or if a short guy has to jump with a tall guy, so what? It's a sport, better that it be decided by a player's physical action than a rule book.
