When the 'not interfering' rule was brought in, the attacker basically had to be walking away from goal with his hand up to prove he was not part of the move.
Since then we've had First Phase, Second Phase, VAR, keep flag down until ball is touched, no offsides after Lent, every bit of nonsense you can possibly imagine.
Football fans are not stupid, they know when a player is involved with the game and when they're not.
The rule needs to go back to what it was. If you're an attacking player trying to attack then you're interfering with play.
