If it has to happen it should be someone in the stadium or a central location watching the game and giving the head ref info as it happens. He can change his call quickly or whatever and that's it. Doubt they'll get it right though, so it's pointless. Only thing I'm adamant about is retrospective bans for diving, off-the-ball incidents, etc.
Saying there won't be talking points anymore because of video replay is so stupid though It'll only cause more controversy, the NFL's had this in place for over a decade and there's still debates over replayed decisions, football is a lot more subjective than NFL. Don't worry about your talking points.
