Good win.
I'm not sure what I would do about Buttler for the rest of the tournament.
Being out of form is no place for an opener in t20. But few people are as experienced as Buttler in India. And it's not like Duckett was in glittering form when he last played.
I definitely wouldn't be moving Jacks; he's playing too well at no.7. And I don't fancy moving Banton either; Rehan in theory could slot in at no.5, but I'd expect his bowling to get smashed in India and his batting is still a work in progress.
The NZ game won't be too important, so it could be a chance for Jos to play with some freedom if he gets the chance.
