Luke Lewis was 95kg wringing wet winger, before the Sharkies "program" kicked in.Luke Lewis was aged 33 when he won the GF with the Sharks and already had over 300 games at NRL and rep.
Gallen was aged 35, and also had over 300.
Lewis played 2 full seasons after that, Gallen 3!
But I agree, those 2 were the exception, a lot of forwards start to decline from about 30. (Brown turns 31 next March)
