Saunders isn't that quick, but he can find his way to the line quite well. He has always had quite a good try scoring record considering he plays for a province/franchise that doesn't use its wingers to their potential. Plus every game he was fit for the Highlanders this year he was picked, so he is rated quite highly by the selectors.
Te Whare as good as he is, you have to remeber that Cooper gets wood over Brew so Brew will always get picked over a player that might be marginally better than him, I would rather Te Whare get picked but it just seems more likely that they will take Brew.
Horton is soo talented it is scary he is just such a stupid footy player, if he could harness that talent and fix his defence he would he very good in the fullback jersey. He just needs to have a coach who will get him to be focused on his rugby and make sure his mind is only on it, so we can see the best of him, As I beleive that we have only seem around 50% of his potential.
MacKintosh has to play super 12 some time, otherwise he will just be another kid who had alot of potential but never played the top level.
