Gamesmanship is a fact of life in the NRL and referees need to be more aware of the lengths players will go to in their attempts to influence decisions and milk penalties, says Warriors coach Andrew McFadden.
South Sydney back-rower Glenn Stewart's stunning admission that he took a dive in a successful attempt to have a Cowboys try denied during Monday night's clash has sparked intense debate about the role of the video referee and the increasing trend of players staying down and faking injuries or taking dives in the hope they will be awarded a penalty.
Video referees are able to review tackles after an injury-related stoppage or any incident of possible obstruction in the lead-up to tries.
McFadden believes the Stewart incident should never have been judged as obstruction and called for referees to be more streetwise when assessing player's motives and actions in such situations.
"It's all gamesmanship and at the moment I don't know if the officials pick up on those little subtleties that players know how to manipulate and that's why [Stewart has] done it," McFadden said.
