1)Buttler is no.1 for me. He is their most dangerous & versatile batsman. Maintaining 118 sr at average of 39 after 96 innings is no joke.
2)roy's ability to dominate pace bowling stands out & that makes him match winner.
/Bairstow earned opener slot & proven to much more consistent and versatile batsman than hales.
3) Root lacks power game but on a difficult wickets his batting offers reliable safety for England. He has lot to offer at no.3 position in future & should be preffered over hales at no.3.
Morgan : proven performer & underrated batsman under pressure. He has brought lots matches close from losing positions & complements England batting order.
