Following on from the thread on the main forum about law changes folk would like to see in football, what's the one change you'd like to see introduced in rugby?
For me it's the laws around the "use it" call at rucks - with the purpose of speeding things up.
The ref to call "use it" as soon as the ball is visible and playable; once called, no-one else (from either side) can join the ruck; referee the 5-second use time strictly, or reduce it to 3-seconds if refs are going to continue to be lenient on the count.
Doing this would not only make rucks quicker, but also more competitive, with counter rucking becoming more of an opportunity to regain possession, or at least disrupt your opponents, rather than not committing players to a ruck, and just letting the opposition take their time to set themselves for a kick from the often double-extended base.
