It led to more stoppages, with some matches lasting up to two hours, and Brown felt it also undermined the referees’ authority with “everyone appealing for everything all the time”.
“Before it came in I thought it could be a good tool in rugby, but on reflection I thought it was unwarranted,” said the Glasgow co-captain. “It was a pretty poor thing to bring in. It slows the game down and it brought referees and officials into question. It challenged their opinion a bit too much.
