Stevens was born in Sydney, New South Wales, Australia. One of his grandfathers was Greek and his surname was Papadopoulos. Stevens began playing rugby league for his school, Marist College Kogarah, in the St. George area as well as playing for local club side the Brighton Seagulls after a request by a friend to join. The then captain of the St. George Dragons, Michael Beattie, recommended that he be signed for the Dragons on the scholarship programme in his mid-teens and he went on to represent the Dragons in the Matthews Cup while still in school in 1991.
Playing career
St. George Dragons
In 1992, after being signed by the St. George Dragons, Stevens moved into the Dragons Under 21s side and reached his first Grand Final for the Dragons but ended up on the losing side going down to the Western Suburbs Magpies. That year he made his first grade debut for the St. George Dragons against the Penrith Panthers at Jubilee Oval on 5 July 1992. During the 1993 season Stevens became a first team regular for the Dragons, playing the majority of the season in first grade and making it to his first first grade Grand Final against Brisbane at only twenty years of age. The day turned sour though when, in the second tackle of the game, Stevens injured his thumb badly and had to be taken from the field to hospital for surgery; the Dragons eventually lost the game without him taking any further part. Stevens enjoyed another four seasons for the Dragons before finally moving on to St. George's local rivals, the Cronulla-Sutherland Sharks, for the new 1997 season.
Cronulla-Sutherland Sharks
Stevens enjoyed a successful and much heralded career for the Sharks. He scored a total of ten tries for the club and put in countless hours in the forward pack building his reputation as one of the best and toughest forwards in rugby league during the span of his career. At the end of the 1997 Super League season Stevens played in his second Grand Final, again a loss to the Brisbane Broncos. Post-season he was selected for Australia and made his International début against Great Britain at Wembley Stadium. The three-match Super League Test series was won by Australia 2–1 with Stevens playing at prop forward in all three test matches. It was on this tour that Stevens helped persuade his front-row partner Brad Thorn to convert to Christianity. Stevens was selected for the Australian team to compete in the end of season 1999 Rugby League Tri-Nations tournament. In the final against New Zealand he played at prop forward in the Kangaroos' 22-20 victory. At the end of the 2001 NRL season, he went on the 2001 Kangaroo tour. Stevens also built up good partnerships over several years at the Sharks and also at International level with fellow Prop forwards Martin Lang and Chris Beattie. During the 2004 season, Stevens retired from representative rugby league after only playing around ten minutes for game 1 of the State of Origin series, though he continued to play for the Cronulla Sharks. In total he played 22 games for the 2004 season scoring a single try. Once the 2005 season began many speculated that it would be Stevens' last and it took several months until any official announcement was made concerning the matter. Towards the end of the 2005 season Stevens finally announced that he would retire from Rugby League while appearing on The Footy Show. The Cronulla Sharks as well as several other clubs offered him new contracts which he declined stating he believed it was time to hang up his boots and move on to other things; niggling injuries are also said to have pushed him towards retirement. In his final season Stevens only made 16 appearances for his club in which he scored one try.
