I do not think that low scorer at Eden Park was a result of two poor teams coming together. Both the Black Caps and the West Indies have ODI potential and it is interesting to look - at what is 'ground zero' for the World Cup build-up - at how our ODI team stack up.
Ignore what happened in the awkward conditions of Eden Park - the top five, the engine room of limited overs batting, look really good. Jesse Ryder and Martin Guptill are proven performers; Ryder won't slap them all to cover and Guptill will hit more straight ones than he misses. These two are an opening combo to place faith in.
Kane Williamson is making strides toward being a world-class cricketer and is key in my World Cup team. However, I would use him in a floating role. If Guptill and Ryder go gangbusters for 10 overs, he goes in next but if wickets are lost in the first powerplay, I would like to see Brendon McCullum bat at first drop.
One wicket should not halt the aggressive approach and McCullum can do a job both early and late in an innings. Two early wickets should also not stop the desire to maximise the first 10 overs of fielding restrictions; so using Luke Ronchi as the other floater could be the way he proves his worth.
Williamson and Ross Taylor work singles and accelerate more efficiently later in their innings; they are two I'd rather not risk in the hurly-burly of the initial overs.
