Yes we had quickies in as well, but the main bowlers where Anderson and Swann, and Tremlett was dropped as he was expensive - despite taking wickets.
Against NZ, I'd say try some new blood. We desperately need a first change bowler who can come in, not leak runs, and pick up wickets. If the selectors think that's Curran, then give him the series. Batsmen, honestly don't know, but give them a few innings to prove themselves.
NZ are a decent test side, but nothing really to fear as far as I can see, so its a definite opportunity to bring in players now. I'd look at possibly resting Jimmy if / once the series is won, on the basis of giving opportunity to others.
