It seems the powers that be are considering anything and everything but the most obvious and practical solution - that is, to use video technology on all important decisions.
If such policing is subject to human fallibility, then surely the easiest option is to make it easier to police my removing human fallibility, rather than changing the rules altogether? That's just a cop out.
Pretty much all the top managers are in favour of it, and I dare say most of the players too. Anyone bleating on about traditions and romance should have a look at rugby, which has survived, nay flourished with video assistance. Not to mention the problems that would be immediately alleviated by minimizing subjectivity in the decision-making. No trying to influence the ref at every opportunity, less home refereeing, less wanker referees seeking back page headlines.
There is absolutely nothing wrong with the rules, and everything wrong with the people and methods used to implement them. The sooner they stop resisting the inevitable the sooner all this ridiculous experimenting and speculating can be put to bed. There is simply too much money at stake these days to ignore it.
