But don't get me wrong, I have absolute contempt for the generation squandering trajectory the blackcaps have headed for the last 2 years. I just don't know yet where to lay all the blame (apart from glaring decline of seam-bowling post Bond)..
Couple points I thought worth bringing up here: to what extent are the Blackcaps actually on a downward trajectory? When New Zealand were carving up in 2013-15, it was generally against weaker sides. West Indies, Sri Lanka, India playing away from home (and even then we won that series by the skin of our teeth) and Pakistan in the UAE. Of those, only the 1-1 draw in the Emirates could be taken as a genuine feather in the team's cap.
Then you compare that with who we've played in the last two years - England in England, Australia home and away, South Africa (playing at home and at full strength), India in India and finally Pakistan. Last season we bullied Sri Lanka just as badly as we did in 2014/15. And we've just finished demolishing the same Pakistan side that drew a series in England earlier this year.
Don't get me wrong, I do think the team is playing worse than when they were at their peak - the bowling and fielding efforts last week were the worst I've seen in a very long while. But I think, more generally, the extent of the decline in performances is being exaggerated (especially given that Baz has left a hole in the middle-order that was always going to be extremely difficult to fill). To a large extent, the win-loss record of the last 2 years is a reflection of the fact that we've just been playing much better teams in that period. Throw in injuries to key players (Boult in particular, but also Anderson, Neesham and Taylor) and at times really poor selection policy (Wagner should've been a regular in the team the moment it became clear that Henry's ODI success wasn't going to translate to test cricket) and I really don't know how much you can blame things on the coaches (or the captain for that matter).
Finally, regarding the "Bond made our bowling attack" theory. I don't put much stock in that either. Southee was already producing fantastic results even before Bond came on board, and the early signs of his decline were there before Bond's departure. Likewise, Wagner is if anything a better (and certainly a more consistent) bowler than he was during Bond's term. While Bond does seem to have be an excellent coach, I think the majority of the blame for the decline in bowling results probably lies at the feet of Southee and Boult themselves.
