Perhaps the best argument for more sports adopting the yellow/red card system is the potential to deploy the cards for comedic effect.
We’ve already seen a rugby ref use the yellow card to rib a ball boy, and this Scottish soccer ref used the red to have a bit of fun at his linesman’s expense.
During Saturday’s Kilmarnock-Dundee match, linesman Andrew McWilliam started feeling a bit queasy and ducked off the pitch to empty his stomach, much to the delight of the crowd. He must not have been feeling that badly, because he had a pretty good chuckle when referee Craig Thomason took the red card out of his pocket.
Had a long night out, did you, Andrew?
He’s a trooper, though. McWilliam was able to carry on and finish the rest of the match.
