If you were talking about playing rugby I’d agree… but with cricket being nowhere near as physical as that sport have to disagree, also in the ODI’S teams spend half the match sitting on their arses in the stands & NZ don’t play that many tests compared to Aussie, England, Pakistan, India & South Africa.
This ODI series is hardly pointless, say for argument sake we did manage to win the series it would give us a slight mental edge against them leading up to the WC & any edge you can get in any sport over a good team has to e a good thing.
It’s not about Pakistan using less players in tests or ODI’s, it’s about picking your best team for the form of the game you’re playing.
