That being the case, and I am not saying it is not, it would seem he was simply not weanted again for the 2012 season. Plausible no doubt. I do question whether it was as simple as this however given that the team has only three genuine wingers - Kade Poki, Telusa Veainu and Hosea Gear. Tamati Elison and Siale Piutau are centres, surely you agree? This is where I am a little suspicious. Sure, I could be totally wrong of course.
About Paterson´s abilities. He did not have a good World Cup. The USA were very, very well organized in defence. Italy needed a penalty try to get the bonus point. Ireland failed to get the bonus point and Russia didn´t score a try. Pretty good. The Australian match was the USA´s reserves so things were not the same. On attack, the USA were the weakest side in the World Cup. Ngwenya failed to score a single try. The team was focused on defence so much that they lacked playmakers at 10 and 12. Nonetheless, Paterson did not deliver. His Super Rugby form saw him take over from Kevin Swiryn - no easy accomplishment. I was thinking, at the time, that the Highlanders would be using him mostly from the bench.
In any event, he is in the USA now not New Zealand.
Quite a big call to say he was definitely the least threatening NZ wing in Super Rugby.
