Its a decent size list of players but its always going to be subjective depending on if you like a player or not. CONEHEAD, Thorn, Lockyer, Alfie, Webcke, Petero, Lazarus etc the list could go on. Payne could potentially be better, but he may not as well.
This current era of NRL suits Payne to a tee. He's an incredible athlete who can churn out big stints and make plenty of meters. At the same time though, i dont see him matching the physicality that somebody like Webcke did week in week out over his career, which you needed when he was playing. Always going to be hard to compare blokes from different era's where the game isnt really the same.
