I think that whomever posted that hasn't done enough research on New Zealand Football. If you look at Wanderers SC, the entire squad is under 20 years old. Also, it seems that "premiership" as in ASB Premiership does not necessarily have the same meaning as in other areas. Finally, if you look at Regulation 10 ASB Premiership, page 13, section 18, it talks about Amateur Player Agreement. This doesn't appear to me to conflict with NCAA eligibility rules. Also, I believe the BigSoccer poster identified that Stuart played for the NZ team in question in January. If playing for that team was an eligibility issue, Stuart would not have been able to participate in the spring matches with the Zips.
