Going to be tough for the Kiwis to win this one with Ryder and Tuffey out. McCullum will need to step out of his shell which doesn't look likely.
I'd assume it depends on who his opening partner is. If Martin Guptill is chosen (and this looks the most likely scenario) I'm guessing McCullum will be told to be the aggressor. If Aaron Redmond play's which looks very unlikely at this moment, I'm guessing he'll be told to try and dominate the bowling.
