Hell, even in today's Aussie side, if you had a 17 year old with 2 years experience at FC cricket and averaging 50+ with the bat, he too would get slotted ahead of one of the off-form/outgoing players (such as when Martyn was droppd/Clarke was dropped/Mark Waugh was dropped/Steve Waugh retired/Lehmann was dropped, etc. etc.)
That's the point though - you wouldn't. There's heaps of examples out there.
There are guys like Jaques, Lehmann, Hussey, Cox, Siddons and many others who dominated for long periods in domestic cricket from a young age without ever being picked.
For a more relevant example, try Ponting. Ponting's debut first class season was when he was 18 - he averaged 46. His second season he averaged 48. His third season he averaged 64. That sounds like he was sitting firmly within the par for good players despite being significantly younger than them, right? He then played a season in England for the Young Australians and averaged 46, and then after a good start to his fourth Australian first class season he was picked for his debut test against Sri Lanka, aged 21. This is all after being recognised from a very young age as a future superstar of Australian cricket and never putting a foot wrong at any time in youth cricket or his early first class career. He was fast-tracked into the Australian team and still didn't debut until his early 20s, because that's how cricket is structured in Australia.
It's doubtful that a 17 year old like in your scenario would even be playing first class cricket in Australia in the first place. It's possible of course, but if you look at Australian domestic cricket right now there are very, very few guys of that age playing. You have to earn your stripes in grade and youth cricket before a state will even look at you. Take Moises Henriques for example - a current prodigy of Australian cricket. This guy has played in two U-19 world cups, and in the most recent one he was the captain, the leading bowler and one of the leading batsmen in the side. He's been marked by many people as a potential star all-rounder, and people have even suggested he could play in the 2007 World Cup, and yet at the age of 19 he is
yet to make his first class debut. He's played two one dayers and that's it. For further evidence, consider that he was the only player in the recent U-19 world cup team for Australia that had played for his state (in the first team) at all in any form of the game.
It's simply a different philosophy to how you should treat young players. There are lot of different reasons for it, but the point is that if you're 16 years old and a massive talent in Australia you'll get put in youth teams, sent to the academy, maybe play a few games for your state, and if you're 18 you'll be expected to have a few solid first class seasons before you get a look-in for the test team. In India or Pakistan, you'll play first class cricket and if you do well and there's a spot available in the test side you'll be in there, and you can earn your stripes in test cricket or you can fail and go back to the first class game. Thus, "prodigies" in Australian cricket will debut in their early 20s, and in the subcontinent they could debut in their teens.
