However, since his arrival he's rarely scaled the heights of 2011, with injury and form forcing him out of the representative picture for both state and country.
But with the Bulldogs leading the NRL ladder with five wins from their opening seven games, he's shown signs of getting back to his best and is hopeful of a shock return to the State of Origin scene.
"I just want to keep doing what I'm doing and hopefully that will lead to a chance to play rep footy," Williams said.
"I always had great pride in playing for my state and my country and gave my best."
Williams could take his first step back to the representative scene when the City Origin team is named tomorrow night - the giant back-rower admitting he'd love to be on the plane to Dubbo with Brad Fittler's side next week.
"Whatever rep team it is I will try my best and I'd loved to be involved again," he said.
"I've really missed it."
