(You might give them a free-kick if their opponent ducks/leans forward to cause them to tumble as well in that scenario, but I don't see that happen much thesedays.)
Have to be careful here. Opponent is entitled to duck. Two possibilities here causing the jumper to tumble. The common one is pushing under a jumping player while ducking, that would a fouls for the jumper. The other is the stationary player is stationary and feels that are being used as leverage, ducking or bending causes the jumper tumble or end up in top and they have only themselves to blame.You might give them a free-kick if their opponent ducks/leans forward to cause them to tumble a

I think a key factor you need to look at is the arms - are they using them to push off the opponent for leverage etc? If they get above a player via a natural jump I don't consider that a foul unless health and safety comes into play - for example, have they jumped over in such a way they're going to land on the opponent?

Quite, I'm looking out for those that are backing in and then deliberately ducking to try and 'buy' the foul. It used to be fairly commonplace when I first started, but I've seldom seen it thesedays.
