Raiders veteran Sam Williams is out to prove he is more than just a stop-gap solution as halfback against the Broncos on Saturday, after the club finalised the release of homesick English halfback George Williams earlier this week. Canberra officials are yet to open contract negotiations with off-contract Williams, who has filled in at number seven for his namesake in recent losses against Melbourne and the Sydney Roosters. The 30-year-old is keen to stay at the Raiders, while recruitment boss Peter Mulholland offered a glowing endorsement of the local junior last week saying he was better than any of the young talent available for 2022. Most of the more experienced halves on the open market who are off contract at the end of this year, the likes of Ash Taylor, Corey Norman, Anthony Milford and Shaun Johnson, are not wanted by the Raiders. Williams knocked back English overtures in the summer, rejecting the chance to join his old club Wakefield Trinity in the Super League despite playing just one NRL match last season.
