Trust me, going a man down for ten minutes will do much more damage than giving moving a ball forward ten yards. Have you ever played the game?
Condersending remark DB! Yep, of course I have played the game! You could get away with a few of the dark arts back in my day!! Not now!!!
Logistical nightmare IMO for a single ref, i'd guess that a very large percentage of refs are on their own in the lower leagues. Potentially it could also cost jobs at the CFAs as it gives you a soft option of putting a player on the naughty step instead of showing a yellow card!
My shout works brilliant in Rugby as the decisions cost an easier FK or even a penalty... Better players will police the culprit players!!!Instant Karma!!!
