I like the fact that rugby carries on regardless (unless the injury is very serious), but then they have rolling subs and there are far more injuries than a football match.
It would be nice to have the football continue, to stamp out those that feign injury to stop the game, but difficult to enforce correctly.
I have no time whatsoever for the view that Rugby Union somehow have all the answers for officialdom.
Why when there is a scrum is the line judge not used to watch the referees blind side. You end up with refs giving penalties for collapsing a scrum, when they have no visibility over who has transgressed.
Why doesn't the clock stop when a kicker can spend half a lifetime preparing to take a penalty. The only people to benefit from this dumb rule is the TV companies
If only footballers behaved more like Rugby players ......and faked blood injuries.
Why when video replays are available does the ref refuse to check if a penalty has gone between the posts ?
On the plus side if football had adopted the same principle for extra time, I could almost certainly have prolonged my own footballing career. I never lost the ability to hoof the ball into touch.
