Since then he's hardly looked back and proven a driving force behind the Cowboys' success over the last two seasons.
"It's refreshing going from the back row into the middle," Taumalolo said.
"The lungs didn't like it too much and I've slowly gotten used to my role in the team."
Moving Taumalolo from the edges has proven a masterstroke by Green and his power and late footwork have made him one of the most effective forwards in the game.
Today, Taumalolo bristles at comparisons between himself and Williams, calling it "not much of a compliment".
"I've had troubles with being compared to him," Taumalolo said.
"We're two completely different players and he had his era and hopefully I'll step into mine.
"How we compare? We'll never know because he's been playing all over in different codes and doing different stuff."
