Sounds like Justin Gulley. According to Rollo's twitter comment.
What's the deal with him? Don't know anything about the domestic league (or much of the a-league out width the nix in fairness).
One of the best defenders in the league, plays for Team Wellington where he's captain - had a short spell at the Nix two seasons ago where he played 8 times. Plays as a right centre back in Team Wellington's back three, but is more comfortable at RB and can definitely do a job in Fenton's role who he's presumably signed to compete with. Made his AWs debut in June this year
