My opinion, he is starting to play dumb.
He is a sniffer type player who should be backing up all and sundry. At the moment he does that part well, but he has assumed that he is now 6ft 6 and bullet proof.
Its not his job to take up the pill as much as he does. One day he will get bounced and bounced hard.
He should be grabbing his bigger bludging mates who have a habit of just wandering around with their hands on their hips, and push them into a position were they could contribute to what ever is happening or could be about to happen. It's not rocket science.
I wish his enthusiasm would rub off on some of the other imposters.
How many times do our blokes get caught out when something goes wrong. They stand around like a group "Sh!t emselves" and the next instance we are on the back foot instead of killing off whats gone wrong.
For example, Sowards try from the scrum last week. Couple of weeks back, when Pom spills the ball near their tryline. Stops, swears, everyone says a team "Sh!t" while the opp just scoops up the pill and runs the length of the field to score.
If Nathan doesn't start using the brain more, and the team stops relying on the little bloke you will see a lot better results during the game. I am worried that he is about to cop some real big punishment.
Same finishing line as Mr Angry ...... Hope I am wrong.
