Will be interesting to see how much of this talent is realised at the top level when the players are older, I don't think a huge amount of players who play at under 19 level get to tests IIRC. Certainly there's a few past under 19 blokes in NZ FC that are either injured or FC journeymen.
TBH out of this NZ side the only ones I see getting to test level are Southee, Williamson, Anderson, Boult and the Daniel Vettori esque spinner. The rest will come from blokes who achieve their potential later on, a few young players already in FC cricket and the black caps (McCullum and Taylor). Have a suspicion Greg Morgan won't get into the NZ team on bowling alone and will try and become a genuine allrounder, he can certainly bat at FC level well (despite being a bowler) but how good yet we can't be sure.
I don't think we'll win but I expect Southee and Williamson to wreak havoc often and Boult and Anderson to have good tournaments as well.
