Ah, but you are wrong. Players have zero incentive to perform if they don’t feel like it due to the ridiculous Bosman ruling.Players receive bonuses & sponsorship, if they keep making mistakes they are dropped so lose out on their bonus & sponsors don’t want to pay someone to sit on their arse, refs are paid whatever so no incentive for them to perform, yes I know some get relegated but this is seldom.
There is nothing subjective about a player reaching up & knocking the ball out with his hand or as in the first shout, leaning over & knocking the ball out with his arm.
All handballs are subjective around guidance given by IFAB.
You could play the identical game ten times with ten different referees and you would get ten different sets of decisions . It’s the nature of the beast.
Speaking for myself it was a very rare event when I finished a game without wondering if I I had made an incorrect decision. It’s the nature of the best.
