There's a few holes in Sibley's technique good bowlers will exploit, haven't seen much of Pope or Crawley, Buttler poor, would rather Foakes.Probably a bit harsh on the openers, particularly Sibley. I reckon he will be a good player. I think Burns is a stop gap. Denly I totally agree with, he's not good enough at test level and at 34 I'd be surprised if they continued to perserve. For what he provides I'd prefer to get games into a young player. Crawley looks like he will be good IMO, add Root and Stokes with Pope (also a good young player that I think will become a good test batsmen) then there is enough there for the short to medium term.
Archer being found out a bit too.
