Over the nine games I'm pretty sure all the seamers will be included and take a full part I would think.
My preference would be Wood, Archer, Woakes but many advocate Curran or Plunkett in the first eleven perhaps for Wood, given Woakes and Archer could open with Plunkett maybe in his speciality, the middle overs. Curran too has shown he's coming good right at the optimum time, and he adds that crucial lower order batting strength that has even recently helped turn a potential batting collapse into a winning score.
Agree Willey is desperately unfortunate, but numbers meant someone had to go and Rashid's ongoing shoulder niggle meant a proper spinner in Dawson was needed.There is still a possibility if an injury occurs in the World Cup tournament to a seamer, Wood perhaps the most likely, then he could come in as a replacement.
In the end the fact that England will be playing all their games, bar the Old Trafford Afghanistan one, on new flat pitches which will be almost certainly prepared under the ICC's normal instructions for hard flat batting tracks with no grass at all, thereby insuring big total batting fests, meant that swing was possibly more expendable than real pace and bounce.
It possibly came down to one of Tom Curran, Plunkett and Willey with the former two edging ahead of Willey given Plunkett's ability to take wickets in the crucial middle overs and Curran's late surge in all areas.
Maybe if they get a semi at Edgbaston on a cloudy day they may want him, but then again given our seamers record with injuries, there must be a reasonable chance he could be available to them by that stage.
