NZ is just not very good in this format and the Windies are excellent.
Narine and Badree are the best T20 bowlers in the world. There's weakness in their batting lineup but as soon as they post a decent total it was always going to be difficult.
This is very much a hotch potch team too. Latham shouldn't be in the team if he's not playing as a top or middle order batsman. Ditto Watling. Sodhi bowled well for the most part but he's not our top limited overs spinner.
Neesham and Anderson also aren't really 3rd and 4th bowlers. We should have another bowler there instead of Latham or Watling.
I think we're just fine in this format, when we have our proper line up. We played with five guys who probably don't make our starting XI when all players are considered. I think the Windies are strong on the back of Narine and Badree as bowlers, with Gayle and Dwayne Bravo being world class at T20 too.
If we select our strongest line up, I think we're Top 5 in the world, alongside the Windies, South Africa, Australia and India and I think any of those teams are interchangeable at the moment too. What we're lacking is a second spinner who can do the same sort of role as McCullum - if Vettori came back in then I think we've got the batting unit, one of the best T20 pace bowlers around in Southee and the spinners to really compete anywhere in the world. It's important we get Ryder back into the mix and I'd argue for Guptill's inclusion too - on the conditon that he just swing for the fences and not worry about the long game.
My line up if we get Vettori back involved would be
1. Ryder
2. Guptill
3. McCullum
4. Anderson
5. Williamson
6. Neesham
7. Ronchi
8. Vettori
9. NcCullum
10. Southee
11. McCleneghan / Henry / Boult - in that order of preference.
Windies are pretty lethal at this format when fully fit too, I do question why someone like Holder isn't in the side based on his control and ability - also his batting, but my Windies line up (fully fit)
1. Gayle
2. Smith
3. Fletcher
4. Bravo
5. Bravo
6. Pollard
7. Ramdin
8. Sammy
9. Holder
10. Badree
11. Narine
Asking for overs from Gayle, Dwayne Bravo and Pollard.
I think those two teams would be a pretty decent contest in all conditions.
