Nah, Southee sucks, Henry isn't as great as we think, and Boult can't possibly keep this up -- he's due a prolonged period of utter mediocrity. Baz is recklessly aggressive and won't come off nearly as well ever again, Taylor's on the downhill slide because he's lazy and Kane's going to revert to talented-but-technically-flawed underperforming prodigy now. Throw in Vettori retiring, Guptill being Guptill and virya's Boy Coriander Sun just not being very good, and things could get ugly. Then Ol' Man River and Luggage are surely out of the ODI reckoning, since they're the wrong side of 35.
The bright spots? Jimmy Neesham's social media presence and, erm, Watling (if he doesn't start sucking too, which he will, because this is the Doom & Gloom thread and he's not a real 'keeper anyway).
Dark times ahead for New Zealand. I predict lots of virya support, funky selection of utter spuds (i.e. Devcich) and losses to Associates in their future. The new England, without the associated upsides.
