The relative inexperience is highlighted by the lack of test caps in each T20 squad.
New Zealand has 161 - Brendon McCullum, James Franklin and Martin Guptill account for 128 (80 per cent). South Africa has 124 - Morne Morkel and Dale Steyn account for 105 (85 per cent).
The selections prove T20 and test skills are now largely treated as different subsets. Only six of New Zealand's 15 test players are also in the T20 squad - there are five South Africans across both. Perhaps a relevant comparison is the gulf in credibility and prestige between playing test rugby for the All Blacks or the recently re-named All Blacks Sevens. It seems there are now Black Caps and black caps.
Selectors know they can bring players into such teams at will while others wait at home. Kane Williamson, BJ Watling and Daniel Flynn are getting valuable first-class matches before the test series while Tim Southee and Jacob Oram awaited the birth of children. Southee is now out of the series with injury.
Nothing is perceived to be lost because it's 'just another T20 series'. One-dayers were similarly maligned for years.
The situation also raises the question of T20's relevance as an international format.
Perhaps it might adopt a predominantly club/franchise model, much like football and rugby, with specific windows for internationals.
Alternatively, international T20 cricket could become a specific genre which also plays a global series like sevens.
