Cameron Smith says longer bans and even deregistrations should be considered for NRL players who disgrace themselves off the field.

The Melbourne Storm captain and Rugby League Players Association general president didn’t hide his frustration after several high-profile players found trouble this off-season, with Greg Inglis caught drink driving in October last year and old videos of representative forward Dylan Napa in sexual acts were made public this month.

NRL chief executive Todd Greenberg had a phone conference with the captains from all clubs last week and told them the game’s senior players needed to demand more from their teammates.

"Todd Greenberg came out early in the week and said that he was disappointed and embarrassed and being in the game myself for a long time I have the same feelings," Smith said.
