I'm never one to usually criticise national coaches/managers, etc. I figure they've got to where they are knowing a heck of a lot more about a game than I do (still makes me laugh when people genuinely believe they could do a better job). However...
Once you get to a point where you're dropping players who are more destructive than your captain (Bell, Stokes) or cant get a look in (Taylor, even Ballance) or putting square pegs in round holes (Hales), something's got to be done. Why not put Cook at first drop if you want to drop Bell for Hales? Why stick a young guy in a position he's never played?
I just get the sense across all British sports that the national staff select through fear. I acknowledge we are a naturally conservative nation, and much more so than Australia, for example, and traits like that embed themselves within institutions, but if there's a time to be bold its now.
That said, we may be saying at the triangular tournament that Hales is in a shocking run of form, Moeen can't play the short ball and Cook is flaying anything short and wide, while Bell is trusting the pitch to hit 360 degrees. So I'll be the one sitting at the back reserving judgement!
