New Rules

NRL open to change if new rules to make game more entertaining don't work

On Thursday chief executive Andrew Abdo said the early rounds of the season will be a litmus test and he is prepared to make changes should the new laws have an undesirable impact.

"Like any change, you have to monitor and we'll adjust if we need to," Abdo told AAP.

"The first few rounds will be critical for us to gather data.

"Ultimately the objective is to create free-flowing football for fans, but we also have to balance that out and make sure we still maintain the fabric of the game and the different skill sets of the different players.
