I may have missed something here......but after Hales' downfall, do we actually need to drop someone else from the World Cup squad? Could we not just add Archer as an extra bowler?
I mean we're pretty clearly going to go with Roy, Bairstow, Root, Morgan, Buttler, Stokes, Ali as our top seven plus Rashid and three quicks.
Denly is there as backup in case one of the batsmen gets injured, or is so woefully out of form that they need dropping.
Why not take all of Curran, Willey, Wood, Woakes, Plunkett & Archer? There's a lot of different styles of fast bowling there. Gives us multiple options, depending on the conditions at hand; plus fast bowlers are much more likely to get niggles or injuries.
I'm not sure having James Vince or A.N.Other in the squad to carry drinks for a month and a half is going to do much good.
