Plunkett misses out for me. He is way down on pace and those figures yesterday were very very flattering when you look at the wickets.
The way I look at this is Archer is basically replacing someone so you need to compare and then swap if neccessary. So Archer will bowl the middle overs that Plunkett will bowl, but bowl them quicker etc... and importantly offers you a death bowling option that Plunkett doesn't really.
Others -
Willey offers a different option so he's in (although it should be on the basis he has to get a haircut!).
Curran is in superb form.
Wood offers the X Factor that is needed on flat ICC pitches.
Woakes is the only bloke who has taken wickets with the new ball, so he's in.
It is a very tough decision definitely and I think the Pakistan series will make or break someone.
