NRL reckons there's 8 minutes lost through players wasting time. New rules are being brought in straight away but will only be enforced with penalties from Round 15 onwards.
The NRL has issued a crackdown on time-wasting in a bid to regain an estimated eight minutes of match time every game.
Rules being introduced this week will require teams to be ready to pack for a scrum within 30 seconds of one being awarded, and the 40-second time limit for line drop-outs has also been cut to 30 seconds.
Failure to do so will result in a penalty, but only from round 15 onwards once the rule changes are properly enforced.
"Due to the fact these changes are to be introduced a third of the way through a season, we believe that a period of adjustment for players and officials to this amendment is required,'' general manager of football operations, Nathan McGuirk, said in a statement.
"Which is why penalties will not be enforced until the start of round 15."
The reasoning behind this is that they believe up to eight minutes of the game time is lost through overly slow packing of scrums and by implication at drop outs.
