Duckett pushed out by Hales/Morgan/Root returning after the Bangladesh tour by the looks of things, shame. Must have been between Duckett, Bairstow and Billings for the two spare batting/reserve keeper slots. Would have taken Duckett and Billings personally, YJB isn't as strong in ODIs and those two are serious limited overs players. Not overly surprised YJB didn't make the t20 squad, not his strength and he's never been a regular for England in t20s. England one day squad is looking very settled now though, with the possible exception of Duckett it's clear the selectors know their best squad.
