I'd have given him longer - decent opener. Anyway, completely irrelevant in the context of KP as they play in different positions. KP is undoubtedly the most talented batsman we've had in recent years, but his acting like an utter bellend has ruled him unselectable it seems, and he's now ageing...
It was Stokes. KP was second, very marginally ahead of Carberry.
