Yep, some good signs. Boult in really good form, Henry the same, everyone seemingly finding some form with the bat.
Still really interested in the balance of the side, whether Neesham plays at 7 and is our fifth bowler, if they play three seamers and two spinners which means Santner is 7, or what they're going to do. We can back Boult, Henry and Santner to do a job with the ball, but teams are going to target the other 2-3 - whether that's Sodhi and Southee, if it's Neesham, if Phillips and Mitchell share overs etc.
The way it looks with the cannon fodder nature of the 5th/6th bowler, I'd potentially go Conway Young Williamson (when fit) Mitchell Latham Phillips Chapman Santner Sodhi Henry Boult. And just hope we can scrape 10 overs out of Chapman/Phillips/Mitchell. Chapman turning it away from RHers and Phillips away from LHers gives some flexibility, and Mitchell can possibly do a job. I accept that's probably going to be messy at times, but much messier than Southee/Neesham? We need the firepower in death hitting.
