Colonel was right, he can defend quite well, it's his size though, he is still a small boy/man and they will test him plenty. Whether he is up to it is doubtful, only due to experience and size not due to technique or willingness in defence. He actually chases and looks to defend. I watched him carefully against the Rooters two weeks ago after Colonel pointed out that he was a decent defender and he did very well he has no fear of the bigger boys and like I said, chases them and more importantly does not miss. But NRL is a whole other kettle of fish though isn't it. Is he ready now? I think if he was brought on slowly, maybe something like K.Keating, then it may just work.
But DA is the best judge of this at this stage, the last thing we would all want is to rush him now to the determent of his long term future as a player by crushing him mentally and or physically due to major injuries.
