Its difficult, because I can make a logical argument for each of the 11 players listed based on their performances in the last year, and I think there is a big difference between a team selected based on performances over a 12 month period and an actual World XI.
As to the former, I think its a pretty decent selection. You could argue Masood or Markram for Duckett, perhaps Santner (for his performances in the India tour) over Jadeja and Rabada over Henry, but in all cases the selections are broadly credible. Travis Head is horribly unlucky that they have largely gone with batting position.
If we were picking an actual world XI, I doubt Duckett, Smith, Atkinson and Henry would be there.
