I'd bring the Neesh back in for CDG, and give Nicholls the boot for Brownlie. I'd say Brownlie's experience and ability to play pace should put him well above Henry for this series. Nicholl's not moving his feet against Steyn, Philander and Rabada will be dead man walking stuff.
Will that happen? doubt it.
Matt Henry needs to be left in Domestic cricket to work out how to take wickets again. Lockie Ferguson made the Blackcaps through his pace and 4 day form. Him and Jamieson are well ahead of the other seamers so far in Plunket Shield. Is he ready for Test cricket? Probably not. Neither is Jamieson, Bracewell and Nuttall are gone, and I would have more faith in Lockie lsting the distance over Wheeler in a test match.
In other words, I reckon we should stay with Southee, Boult and Wags through lack of options more than anything.
