Its hard to judge players that were always part of great teams, Lockyer debuted into a dominant broncos team, but even early in his career he had already won premierships, won a clive churchill medal was a test regular and captained an origin series win. All notable achievements and he was already a great player but the thing that makes him an immortal in my books is that around the time he got the Australian captaincy until about the day he retired he was always the best player in whatever side he was in. Those stacked broncos sides, Lockyer was always best, that great Queensland team that had thurston, Smith, inglis etc Lockyer was always the best and the go to man at clutch moments. That also flows onto the test team. That's at least 9 seasons od always being the best player in your team. Provan only became captain coach for 5 or so seasons and by then Raper and Gasnier were in the team, Meninga was always behind lewis in the 80s and by the end of his career it was stuart and daley who were vital to that Raiders side
