Then there's Peter Fulton, 1 and 0 at Sabina Park, the second innings a dreadful shot which betrayed an edginess and cluttered mind, and who can't buy a run right now. Does Hamish Rutherford get a recall, or do they opt for the status quo after such a convincing win?
And how about Corey Anderson. If over his neck injury, how do the selectors find a place for him? There's plenty to ponder, but that's for later. After dominating the first test from the off, New Zealand should savour a job particularly well done.
Kane Williamson's sixth century, Jimmy Neesham's second and Tom Latham's encouraging start to life as a test opener, 83 and 73, laid the groundwork; Tim Southee and Craig led the bowling operation.
The West Indies are a world away from their epic era. Even so, more was expected in their own conditions. Still, that's not New Zealand's problem.
As that 10-test winless run last year rolled along, Brendon McCullum and coach Mike Hesson insisted good things weren't far away. This was viewed with scepticism at the time. But they have been proved right.
There are good reasons for optimism. The bowlers worked effectively, the first innings batting was again impressive and in Craig New Zealand have uncovered a highly encouraging spin option.
The maturing of this team, the pieces nestling in place, and Craig's debut which hints at good things to come, are all immensely satisfying. The self-belief is there for all to see.
