New Zealand line-ups are so weird. Three wicketkeepers (Latham, McCullum, Watling), two pace bowlers (Boult, Southee), one spinner (Sodhi), one pace bowling all-rounder (Anderson), three spin bowling all-rounders (Craig, Vettori, Williamson), and one specialist batsman (Taylor).
They've always been like that though. Personally I think it's part of the fun.
