He looks big enough to playing some first grade soon.
I think the main indicator of how far off the club thinks he is is that even in the most dire of prop shortages we've had this year, he still hasn't managed to find his way into the team. And that's not a knock on him, he's just really young. He could play Flegg for another year or two at least but we've already got him up a grade seasoning him against bigger bodies already.
The thing is there's a very wide gap between first grade and cup as far as being a middle goes. The NRL is insanely physical and fast compared to any other Rugby League. Maybe he will be capable of a serviceable 15-20 minutes off the bench by the end of the year, I dunno. An NRL middles' body isn't built overnight, or even in a single year/off season. Turning kids into NRL players is like tempering steel - especially for a prop. I'm not expecting anything out of him this year except for *maybe* getting a small run towards the end of the season if an injury opportunity presents itself - just to give him a taste of what the NRL is like and where he needs to get to. Maybe he'll see a bit more bench time next year if he keeps kicking on. I wouldn't expect more from him than that.
And that's not to say he's not brimming with potential, it's just to say he's 19 and the NRL is really, really hard. If we have him delivering regular minutes from the bench by the end of next year we've probably done well to accelerate his development even.
