Super rugby has definitely tried to speed this up, as well as injured players, if they can walk get them off the pitch and treat them or get back in the game.
Seen a few SH players comment on the NH game too on socials about how often the water carriers come on and hold the game up.
I have a few die hard RL fans and they constantly mock unions ‘time in play’ statistics. Of course different to league with their versions of line outs and scrums but we definitely need to speed things up to keep the attention of fans, especially at international level. Water boys, lineout meetings and scrum resets are a growing contributor to this
