That delivery is as close to actually unplayable as you are ever going to get - the only guy with a hope, ironically, would be the rabbit tailender poking his bat nervously where h thinks it might go - and then only by pure dumb luck.
On selection, I would not rush to throw baby out with the bathwater here. A lot of the difference in this series has been down to conditions that suit one team massively (same squads in English conditions, we win), and to a lack of conviction in the England side arising from the Bristol incident and von Strauss' apallingly bad management of the situation. Ask yourself, had that not happened, would the series be the same (no - we would probably still lose, but it'd be a lot closer).
In terms of selection, the only real issue I can see is around the bowling being so samey. That is not an easy one to solve and anu solution would have been a mahoooosive punt. Some have mentioned Plunkett, but he has taken single figures of first class wickets in the last two seasons, others have asked for a left armer, but the options - Garton, Footitt, Sam Curran, Willey etc - are not of the required class (yet).
If we lose here, I'd like them to make changes - blood Foakes and Curran, perhaps Crane too - ahead of the tour in four years time. But come NZ nothing much will have changed.
