Yep, I reckon we should bite the bullet now, and commit for two years to a top 6 (injury permitting) of
Latham
Rutherford
Williamson
Taylor
McCullum
Anderson
Not completely sold on Rutherford, but the likes of Flynn, Redmond, How, Guptill etc are a step back - Flynn would be my choice, but Rutherford needs to iron a few things out and he'll go ok
Not yet convinced by Anderson in tests either, but with Ryder being Ryder, it's Anderson's slot - I guess the likes of Neesham, Munro, Cachopa and in a year or two O'Donnell will be in the wings
