Meanwhile, the form of NRL superstars Jarryd Hayne and Billy Slater is behind the move to devise a new ''downtown'' rule, designed to give every fullback more room from kick returns.
Referees boss Robert Finch yesterday made no secret of the fact that the success of the leading fullbacks in the competition last season - and the resultant tactics by coaches to counteract them - prompted the crackdown on opposition players being offside when chasing kicks.
Under the new rule, players who stray in front of the play-the-ball before the ball has passed over their heads from a kick will be called offside by the referees, and penalised if they continue to advance. Finch admitted the purpose of the rule change was to give the likes of Parramatta's Hayne, Melbourne's Slater and the Cowboys' Matt Bowen more time than they have had before to take kicks from general play - not attacking chips, bombs or grubbers.
''If you give them an inch, they'll take a mile,'' Finch said, referring to the players who head ''downtown''. ''If they stop and don't continue to run, we're comfortable with that, but when the kick goes, those fullbacks and wingers should get the space that they deserve.''
Finch believes some coaches have identified the impact of dynamic fullbacks running from the back, and have attempted to nullify them through the tactic.
