Val homes did it and did it better in his short stints. Why are you talking about the centre he was outside of? The work comes from the Smith/Lockyer/Cronk/Slater/thurstons - then the centres, then the winger. He was lucky enough to be on the end of a backline that allowed him to score 5 tries in a game, and so on.
He was lucky enough to be around at a time when he could benefit from being outside those excellent players in rep teams. He was good enough to play his role nearly perfectly for a few years playing fullback for excellent teams. We all saw how shit he was for teams that were not great, and we all see how shit he is not when everything isnt laid out for him on a platter.
Imagine if boyd was playing fullback in the 09 eels?? fuckin LOL
The reason people can acknowledge that those other blokes were excellent, is because they were excellent. Its got nothing to do with supporting a winning team haha. Thats the difference lol. They were excellent players in shit or not amazing teams who carried their teams for periods of time (Hayne more so). Boyd has been a slightly above average player in excellent teams and is elite at what his role has been in those teams. No one would ever pick peak Boyd over a peak Hayne/Slater/Tedesco/Barba/Inglis and so on, and its as simple as that.
Yes, he has had a wonderful career. Its been said. But he has been a serviceable rep winger outside of immortals and an above average club fullback behind great teams. Very lucky player and he has done some things that no one else will be able to do, purely because of timing.
