I'm a liberal on handballs - I think they're called way too often and we need toHandball rules are like catches a couple years ago in the NFL. I don’t understand it and neither do the refs.
The ones I want gone are the ones where the arm is dangling at the player's side, not extended (so, not the defender "making himself bigger"), but a powerful kick hits it, and the arm recoils visibly so it's easy for the ref to see that it hit it, and all the IFAB guidance in the world isn't going to change their instincts to call that.
