Don't know much about the others but seen a bit of Billings and Ansari when watching kent & surrey. Sent think Ansari would get a go but a decent bat and not a bad bowler plus being gun in the field so he does cover all bases and has been a regular for Surrey since a very early age I believe.
Billings can be a game changer and his keeping has come on as well, could be a threat to butler in all forms moving forward and I personally have championed him for a while, probably on part to being a kent fan lol.
But in any case no 11 could do worse than the tried and tested from the WC, would love to see 5-6 of these play regularly moving forward with the addition of the quality and experienced players who can play the modern way sun h as butler, Bopara who I have always liked as a player, Morgan, Root etc hopefully some positives from Engkand in the short format over the next 18 months or so
