I suppose pretty much anything in selection is possible , I'm a big fan of Foakes keeping but with Stokes coming back how would you get all 3 of stokes,butler and Foakes in the same team?
Crawley could well open if one of the current two stayed home but that still doesn't really work.
Butler has I believe scored well in the sub continent so it's not a daft idea by any means, just can't see it in practice.
Would they want to leave out Pope and play Butler at 6 with Foakes behind.....
