Some players are just late bloomers, nothing wrong about that!
It's possible Robson could continue to improve his attack and kicking game.
He has shown he has mental toughness, is disciplined, does not get scattered or unsettled and provides a calming influence over the team.
A good five months training in the off-season with DA, (Johns & Sterling when they can help) and with Daniel Mortimer, Hayne, Mateo, trainers/conditioners/sprinting coaches, etc, etc, and with the very successful last season resonating behind him, Robson's confidence and attitude could possibly have him improve another 50% or so.
Robson has also shown he tackles just as hard and passionate in the 78th minute as he does in the 1st minute... this is an attribute of great importance to DA and the team. Robson is a proven 80 minute player. Kris Keating has a way to go in this department (the power, intensity and the passion in defence etc).
I guess for next year that KK will be a 14 come back up 6 or 7. It's up to Robson to lose his position and I just don't think he will let this golden opportunity slip through his grasp.
Mortimer will improve in attack next year, as will a fitter, stronger, faster Mateo and Inu. Then we have Hayne & Tahu...... and there is the Keating brothers, Burt & Anthony Mitchell if he manages to break into the top 17.
The Eels won't be dependent on an attacking 7 next year but they really could do with Robson being an 80 minute perpetual motion machine cleaning up both sides of the ruck, up the middle and out wide.
We will all know by the 6th round if the Eels have upt the anti to much greater hights than the ones they achieved late this season.... with the unpredicatable style of turning/passing at the line launching 2nd phase plays being the undoing of all defences before them. They will most definately be mentally tougher than this year. And then there is Poore & Shackleton, both will become internationals.
