I think we agree that current practice is to allow the chaser to jump for the ball, on the assumption that the opponent will also jump and that such a collision in the air is less likely to tip a player over (the main risk of serious injury).
Whether we agree or not, surely we agree that an individual referee choosing to act differently would just confuse the players and might end up making matters worse.
What we can sensibly discuss is theoretical alternative approaches, and the main one is saying that if an opponent is in a position to catch the ball, a chaser cannot jump for it.
If the chaser is still allowed to challenge for the ball, for maximum effect he will arrive just as the ball does. This will usually flatten the opponent and frequently mean the ball goes loose, leaving the referee to decide if either player knocked on.. Being thumped backwards by an opponent arriving at speed does not sound particularly safe to me, even if you reckon it is an improvement over allowing the jump.
What about the catcher? Is he allowed to jump at the last minute to have a better chance of getting a good catch, knowing the opponent is not allowed to jump? If so, can he be tackled in the air? No. So the chaser now waits for him to land before flattening him.
If we want to defuse the situation, I think my Fair Catch proposal would do the job very nicely: player signals, referee shouts "Fair Catch" to acknowledge it, chaser knows he cannot act unless the catch is spilled. Most of the time the current airborne challenge would be replaced by a scrum (which may not be to everybody's taste :biggrin:, but you can't win them all).
BTW I would hope somebody is collecting statistics on how often one or both players get injured in such situations as a way of evaluating the risk in practice.
