The "technology" of a fat middle-aged man watching a TV screen was ancient and obsolete before it even arrived. I give it 5 years until the ref gets a signal in his clock saying, with AI judging if its a foul or not, if its supposed to be a goal kick or corner etc.
Indeed. Bit of a no-brainer.
Like saying "there would be more goals if we quadrupled the size of the goals". Sure, would certainly be the case. But would it be more fun? More tense?
