Bruton was clearly the best player in the league when he signed even at advanced years. Brasswell was the best import (at you expect decent money), then Jackson.
Chuck in Penny, Corleto, Wilkinson and a couple of others I can't name off the top of my head and they regularly have a starting five better than any other side in the league. They are also helped by the fact that the best kiwi players aren't all overseas like NZ football as the opprtunities are more limited.
Remember just about every other club in the league (and the league) has been within inches of folding in the last five years. They are well funded compared to the other sides in the league. The Phoenix are not.
