They would show flashes of it, yes.
I don’t expect every great half back to hit the ground running, but you’d see glimpses of what they’re capable of after 60 games. We’ve seen basically nothing from Nathan in terms of being able to create tries for his teammates.
Age isn’t the relevant factor either, experience is. 60 games in the NRL is more than enough to give a good evaluation of a players strengths & weaknesses.
You're right. Players dont ever improve after their 20s or evolve under new coaches. Nathan has peaked.
And yeah he hasnt even shown glimpses of being able to create tries. Oh unless ofcourse you've actually watched him play. His strike rate might not be as high as you like. But he has come up with some very nice try assists. Shown good vision a number of times on when to kick rather then pass. Or run himself before linking with others. As recently as 2 matches ago.
As he matures he will be able to use his experiences to more frequently come up with the right plays in situations like that. Throw in a new coach who will let him back himself and there's plenty of reason to be optimistic about him.
That's not to say it's a guarantee he gets better. There's no blanket rule for how players develop and evolve. He could very well have peaked already.
But when a player works as hard as Nathan does to improve. I am going to back him to do so. But on a new big deal he will certainly be held to a higher standard.
