Safety approach at grass roots level.
This season allowance for advantage play at scrum time has been highlighted. Ball must be at the back and ready to emerge, front rows go down and if safe to do so, advantage can be played and ball back into play. The idea to reduce the number of resets.
Note of caution.
At grass roots and lower levels of rugby this asks a lot of the ref to make a call the collapse is safe and players not at risk. Safety call would be call it and reset. Advantage at scrum may be easier to play at the higher levels of the game.
