One who knows about young fast bowlers coming into a New Zealand side is former quick bowler and national selector Dion Nash. Also selected as a 20-year-old, Nash made an impact early in his career - he took 11 wickets and scored a half-century in his first test at Lord's - was injured and then came back to complete a career of 32 tests and 81 one-day internationals.
Nash believes the best way for Milne to make an impact is if the senior and other medium-fast bowlers in the side can hunt as a pack - and do so more effectively than they have managed in the recent past.
"If you look at whenever a young guy comes through as a fast bowler in Australia, you see that he comes into a system which supports him," said Nash, who was not just talking about supporting the newcomer mentally.
"The young guy usually comes into a winning team and he is usually slotted in among senior players who bowl as a unit. They have a game plan that they stick to and the young guy knows what he has to do."
"I really don't want to sound negative and I don't want to be one of those former players seen as just bagging the team. After all, Milne could really grab his chance and this could be a real breakthrough for him.
"But you'd have to say the Black Caps aren't doing that [bowling as a unit] well at the moment.
"Tim Southee is still finding his way, same with Trent Boult and even Doug Bracewell. They will need to get some real input from senior guys like Chris Martin, Kyle Mills and Jacob Oram."
Nash said the New Zealand team management and bowling coaches had a big job to do to get the bowlers working as a unit and slotting Milne in.
"Look at South Africa. When you see their quicks operating, you get a real sense they are working to a plan and that they all know where they fit in. With our guys, it's more like 'let's give this bloke a go' and they come in and try and bowl a collection of licorice allsorts.
"The South Africans are learning lessons from their T20s, I'm not sure you can say the same for us.
"I should temper everything I am saying by making it clear that I am glad I was not around for T20. It's really put the cat among the pigeons. When I was playing tests and ODIs, I worked with Chris Cairns, Shayne O'Connor, Geoff Allott and Nathan Astle and the other part-timers - and we worked to a plan. Often it was as simple as knowing that if 33 per cent of your deliveries were maidens, you never lost a test. So we worked on starting strong and ending strong in our overs."
"T20 is a hard ask. It's a lottery. If you get collared in ODIs, you can really have your confidence in other forms of the game affected.
"With T20, it is part of that game to actually get collared and that doesn't change what it can do to a player's confidence."
