I never got to see the King in his prime, but I havent seen many players able to control a game quite like Johns. In every aspect of it. Wally Lewis was complete. Had it all and a bag of tricks. Johns was the same IMO.
Joey could absorb a game plan like no other, coaches often say that was his best aspect.
When talking Immortals, I think that title should go to players that had a forever lasting impact on the competition. Like Churchills taking on the line through defenders, Raper, Provan and the rest of that Dragons foward pack, they had to introduce a 4 tackle rule to stop their dominance, the way Coote would run lines through the defence, Fultons near perfect timing when chiming into attack , of course Wally Lewis and the impact he had on the Origin arena, the security he gave his team mates, and then theres Joey, his kicking game was revolutionary. The control he had on the ball was magnificent, and let alone his vision, passing skill etc etc, his kicking game made him a fullbacks worst nightmare. Another thing on Joey, he was able to bring the best out of his team mates, get them the ball in situations where their abilities would be best served. I point to Matt Gidley being a prime example there.
Lockyer to me isnt the complete player in my eyes. You could put Johns in a defence line and be sure that he wont be a liability, but Lockyer still has that about him, defence wise id much refer Johns. In attack Lockyer was and is still the greatest opportunist in the game. When ever there has been a sniff of blood, Lockyer was right there to capitolise. But he doesnt have that aura that the other immortals had. If Lockyer is better then Johns, then so is Fittler, Daley, Stuart, Langer, Lewis and Sterlo.
Jarryd Haynes form late last year was something special, but the best players keep reinventing themselves and continue to dominate.
