He wouldn't be up to NRL level.
He does hit hard but of all the times I've seen him play he hasn't done that much on attack. He has size but doesn't seem to have any strength to stay on his feet, push guys off, offload. Those sorts of attacking things that big guys need.
If he got down to about 135kgs and worked on his agility, fending, offloading he would be a lot more useful IMO.
