For me offside should only be the players feet, easy to manage. Even for VAR.
What I can't abide however is the second phase nonsense. Lino keeps flag down, play goes on and then if there isn't a goal it's never looked at. ( A corner with rangers and dessers against us ). I see this at all spfl levels. What's the point of the lino of not to raise a flag?
A slightly different take on this is ( and kyogo is a master of it ) standing ten yards off with your hand up. Winger runs onto the ball and then delivers into the box where you're ahead of the CB because you had a ten yard start. Utterly ridiculous. If you're off, you just should'nt be allowed to get involved.
