Thurston is the only current day player who should lay claim to a future immortal title.
Lockyer is another player who deserves immortal status because he could turn a game and win pressure games with clutch plays.
Inglis, Smith, Slater are good players but no where near immortal status. Just because they play in successful teams that does not mean they are immortals.
Slater is made to look a lot better then he is because of the teams he plays for with Cronk as his halfback. If Slater played in a team with Pearce as halfback he would be a good player but not the freak that he is. That takes away immortal status in my opinion.
Smith is a great captain and leader but a myth as far as footballing ability goes. Yes he is a good player under pressure, but the last time I checked that doesn't give you immortal status. Give me Issac Luke over him every day of the week.
Inglis, the NRL love child. Yes he is big, yes he fast but that doesn't mean he is an immortal. Look at him now in a struggling Souths side, no where to be seen. The true immortals find ways to make the big plays and get their team out of a hole when the going gets tough. Players like Johns, Lockyer and Thurston were able to do that and that is why Inglis isn't in their league. He has always shone in successful sides but now when the going gets tough Inglis is being exposed for the myth he truly is. Good player but not an immortal.
I've heard some people say that Gallen should be considered as a possible future immortal. Please, the bloke is a significant step below Slater and Inglis let alone becoming a future immortal.
What about Tedesco and Brooks future in Rep footy?
