WITH Gareth Ellis heading back to England, the Wests Tigers have made an approach to Sonny Bill Williams. SBW's agent, Khoder Nasser, was approached by Tigers football manager Warren McDonnell. It's unclear if the talks will go further - Williams is widely tipped to be keen to join the Roosters but no deal has been done. I was told Benji Marshall was keen for his club to chase his good mate Williams. "Of course we'd like Sonny, which club wouldn't," he said. "But that is not my department - that's up to the club. I'm not the one pushing that line." SBW's next step in football will definitely be a big event, but when a deal is struck with his next team it will involve boxing. Those who love to knock his ability to fight should note he has just rejected an offer from legendary promoter Don King to join his stable of boxers. King's people went through the New Zealand Boxing Association to make an approach, but Williams will do things his way. He is also set to ignore approaches from at least two other American promoters. All this during a week in which former Swan Barry Hall decided boxing was too tough. Hall took some delight in saying he didn't want to be regarded as a novelty fighter like SBW. He's in no danger of that happening.
