It's a challenge George Williams is relishing. But the hard-as-nails Canberra Raiders halfback refuses to make the mistake of giving David Fifita too much respect. Williams has a job to do when the Raiders face the Titans on the Gold Coast on Saturday night, only part of which involved stopping the barnstorming second-rower. Fifita's scored three tries in three games since switching from the Brisbane Broncos to the glitter strip. The Raiders right edge of Williams, Hudson Young and Sebastian Kris will have the job of keeping Fifita's impact to a minimum.
