Football (The real one) has been sorely lacking in the rules department for a long time due to this thing they called FLOW.
Even since the Japan and Korea World Cup where video screens and instant replays clearly show to millions of people what is going on, referees refuse to use video replays as evidence.
It is to my understanding that American Football allows a certain number of times for the coach/manager to call for a video replay.
3 times a match each side seems fair, you can only use it when necessary and it still keeps the game going
