It's become an obsession with legalities over common sense. The offside rule should return to a position whereby lines are drawn on a screen set at an agreed distance and if it's not obvious the player is offside then they are onside. This would speed the game up. Some will go for you and some against, which is no different to how things were when the decision was up to linesmen to make. But it will be quicker which is what is needed.
In terms of the handball rule - needs to return to ball to hand or hand to ball.
Regarding fouls/dangerous play etc - it needs to be viewed in real time predominantly. Anything slowed down looks worse. There could be no intent to harm in real time, it could just be late. Which would be a booking. But when slowed down it looks violent and serious foul play and is a red. That's nonsense.
Cancelo's sending off yesterday, according to Walton (aka idiot), was because it denied a goal scoring opportunity. Welbeck "could have" had the ball under control and gone on to score so it had to be a red. That's all fine and I totally agree. But take your head out of your rule book and watch the incident... Cancelo takes a poor touch but would have been able to hook the ball somewhere, if not for Welbeck wrapping his arm around Cancelo's and dragging him to the ground. From the referee's angle it looked as though Cancelo was responsible. From the angle VAR had it was clear Welbeck fouled Cancelo.
