It's all well and good promoting a trio of young middle order hitters in Colin Munro, Jimmy Neesham and Corey Anderson - all swing a solid, effective bat in the short game - not to mention have a fast-medium attack in which Doug Bracewell is the senior figure.
But once Ross Taylor withdrew, and Tim Southee, Dan Vettori and Jacob Oram were ruled out for various reasons, there must have been a case for getting an extra older head or two in the group. A case in point being Kyle Mills, who took five Canterbury wickets yesterday, or Kane Williamson for that matter. Not required, said the selectors.
Don't be surprised to see the XI chosen for tonight backing up again in the opening T20. That is the norm, to at least get them into work before the first big contest.
Bet on McCullum wanting to assert himself at the first chance.
Fair enough too. This is a daunting challenge, but he's always appealed as a player who likes to take on those sitting at the top table.
He has labelled the tour as "a really exciting time" for the newcomers.
"We're going to find out a lot about the new guys in the next little while," he said.
McCullum is over discussing who is not on tour, and preparing to work with what he has at his disposal.
"From a leadership point of view, we've got to find a way to use the resources we do have, rather than focus on what we don't have," he said.
Australia have retained the Rose Bowl women's cricket trophy in remarkable fashion, with opener Meg Lanning blasting 103 off just 50 balls in Sydney yesterday.
The target of 178 was reached in just 21.2 overs, with nine wickets to spare.
