Ansari isn't an opening bat really - he is doing the job at Surrey because he has the mental ability to bat for long periods of time. I think he should be more of a 6,7, or 8 personally.
I loathe the expression "not ready". I would pick Lees now and stick with him. He has a cricket brain and will work it out.
Gutted for Hales who I think would be brilliant, but has been messed around with.
At the moment our team looks a little short of batsmen who make a bowling attack loose sleep.
Cook, Mr X, Bell, Root, Taylor, Stokes, Bairstow, Ali etc won't strike fear into any team.
Cook, Hales, Root, KP, Taylor, Stokes, Buttler, Ali - should - but we will need to accept that Root will frequently be in early and KP isn't going to get picked. Plus the Eng management have ruined Hales and Jos somehow.
As for Bairstow - I haven't got him in the above, but I recognise that he should be based on the number of runs he has scored.
