Re logistics its shorter plane flight UK to stateside than NZ to the US of A - so don't follow your logic at all. Plus Graham's actually playing in season. Stirling Sports Prem has yet to start.
If Doyle, Wynne, Colvey, Fenton are all out with injury - then Graham must come into the AWs squad reckoning. League One is a pretty reasonable comp, to be playing in - even if he has only started the one game.
