Except that NZ doesn't have a great track record of selecting young bowlers out of domestic cricket – they're either injured in short order or turn out to be not very good.
There's also the question of which five you would drop from the following: Henry, O'Rourke, Jamieson, Duffy, Sears, Foulkes, Rae, Tickner, Smith and Fisher. Certainly there are one or two obvious candidates, but five is a mite tricky.
O'Connor looks to have potential, but there's nothing much to be gained by rushing him.
Henry and O'Rourke are locks, as is Jamieson on reputation and record but imo I fear we've seen the best of him at this level.
Then you'd think it's Duffy. You can't not include him after the home summer, but I also fear he'll fare overseas much like he did in the T20 world cup once let out of NZ shores, but I'm hoping to be proved wrong because I love the Duffman.
Foulkes
should be left out. Fisher would be a risk given his injuries, Rae was a stop gap and then there's Nathan Smith. A sort of heir apparent who has done ok with his chances but hasn't really cemented them. A bowling Will Young if you will. He's got batting in his favour but not much else. It's a shame, because I am a fan. Sears is an unknown quantity. Has played one test and hard to tell where he is in the long format pecking order.
But yeah, O'Connor should see if he can pick up some club cricket in England and be on call when one of our quick inevitably breaks down. Entirely possible they may name a slightly different squad for Ireland but I feel like that will be treated as a warm up for the England series, so doubt there will be much different.mind you, given it's four tests in England, I wouldn't say 6 seamers in a squad of 18 isn't out of this realm - heck neither is 7. Imagine they won't give Patel a gig and Santner, Phillips and Ravindra will fulfill any spinners duties.
Assuming fitness, I bet NZC will go with a squad like:
Latham
Conway
Williamson
Ravindra
Mitchell
Phillips
Blundell+
Henry
Jamieson
Duffy
O'Rourke
Santner
Smith
Hay+
Young
Nicholls
The other two spots I genuinely don't know. Possibly Sears if he's considered a more exciting prospect, and more "polished" than Fisher. Though given it's England they may think Foulkes will be a handful.
And then maybe another backing back up in Mariu or Heaphy if they don't take Patel. Conservative pick would be Kelly. The A tour to Sri Lanka should give us a bit more of a clue though.
