You dont need to floor someone for it to be a foul. If you want on that then theyd never be given.
No one thinks you need to floor someone but you have to do something that causes a disadvantage to the player illegally. If you barely touch him and it doesn't effect any part of what he is doing, how is that a foul?
You dont even need to make contact lmao. You cannot kick someone...regardless of whether it would floor someone or not.
So is any contact at all in the box a foul if the attacker goes down? Thats pretty much what you are saying. Regardless of whether it gains the defender an advantage or penalises the striker.
I'm not even convinced I can see any contact at all let alone enough to be a penalty. The only contact is when he leaves his leg behind as he dives.
