I get what you are saying, but imagine being on the other end of that challenge.
Not such a problem for our elite players but, a grassroots player on the other end of a similar challenge then can't go to work the next day coz his legs snapped in two. Just one of those things? I'm not sure I agree with that and subscribe to how
@GraemeS puts it. He has to take enough care of win the ball cleanly and not almost break his opponents leg.
Agree it should be seen in real time BUT point of contact it specifically says to use freeze or slo mo. I don't think the freeze or slo mo enhance the severity of this challenge in anyway.
You show him where he catches him, then show the force at full speed the only outcome is a salutation, and it's not a hello.
