How can black card issue be an experiment if it’s already in rule?

Steel yourself: it’s coming very soon to a field and a radio and paper near you.

Not only will you have managers condemning the black card, but you’ll have commentators condemning managers for condemning the black card.

It’s invariably how GAA Januarys go. Some new rules are brought in and as referees raise their arms to raise cards, managers are up in arms as well. We had it with the sin-bin in 2005; the same again in 2009 when players were replaced after a yellow card; the mark in 2010. Before the rules were even given a chance, the managers were giving them the red card.
