Overall I think the current crop of All Whites are technically superior to the 2010 vintage squad (thinking of Plodder, Mulligan, Bertos, Lochhead, Boyens, Barron, Sigmund, Bannatyne)
Tzimopoulos and Tuiloma will potentially form a central midfield at least as good as 2010.
Wood, McGlinchey, Reid and Smith are now much more experienced than they were in 2010 when they were just beginning their All Whites careers.
Having watched most of the games in the recent Copa America, it seems there has been a levelling out in standard with anybody capable of beating anyone.
Venezuela (traditionally the weakest team in CONMEBOL) beat Colombia in the group stage and were very unlucky not to make the quarters.
Peru was one of the better sides and made the semis, were unlucky to lose to host Chile and finished third.
Bolivia were not a bad side either and their only loss in the group stage was to hosts Chile.
Brazil were rubbish and deserved to go out to Paraguay in the quarters. No Brazil player scored more than one goal in the tournament (only five Brazil players scored - one goal each).
Uruguay and Colombia only made the quarters as the two best third placed teams in group play.
Argentina struggled to score before turning it on and scoring six against Paraguay in the semis - they scored only four goals in their three group games and their quarter-final (even beating Jamaica only 1 - 0).
To give some idea of the relative strength of COMEBOL and CONCACAF, guest side Mexico finished bottom of their group beneath Chile, Bolivia and Ecuador; Jamaica were bottom of their group.
