Matt Scott has literally had a front-row insight into the evolution of Jason Taumalolo.
Scott revealed his "frustrations" watching Taumalolo fail to recognise his full potential before finally becoming a star with the Cowboys last year in their charge to the premiership.
That evolution continued this year when Taumalolo shared the Dally M medal alongside Cooper Cronk.
Scott will go head to head with his club comrade in the Four Nations final when Australia play New Zealand on Monday.
"He is one of the hardest to stop in the game," Scott said. "We've all seen what he can do this year. His last game (against Australia) was a lot better than it was in Perth. He is someone we have to contain in the middle. You've got to work together on him. You can't do it one out. Hopefully he doesn't bring his best."
