It's extremely hard to break into first class cricket in Australia, simple as that. No doubt Tendulkar would have been into the first class setup earlier than most, but it's pretty unlikely he'd have been playing any earlier than 18 or 19.
People dont realise how precocious a talent Tendulkar was.
When you got a 11-12 year old kid playing U-15s or U-16s and averaging near bradmansque figures, it definately merits fast-tracking and i dare say if Australia or anyone had someone that precocious, they'd have played him at FC level at 16 or 17.
Its not a question of the setup- its also a question of talent. I agree today it'd have been extremely hard for Tendulkar to break into the Aussie team before he was maybe 19 or 20 but back in the time he came in, he could've cracked any team within a year or two of what he did.
Its not like he didnt earn his spot into the team !
True, he scaled his greatest heights (so far) in his mid 20s but his test record before he turned 21 was : 2023 runs from 45 innings, 5 not outs, 50.57 average, 7x100, 10x50 and only two matches against Zimbabwe amongst it (62 runs total) against a minnow.
Agreed, he bashed SL good in that period and SL were a weak team but no weaker than a bond-less NZ or cairns-less NZ in the 90s. Took England and to an extent Australia to the cleaners as well.
This also at a time ( 1991 to be precise) when a grand total of THREE batsmen were averaging 50+ apart from Tendulkar - Viv Richards, Alan Border and Javed Miandad- all three, who were comming to the end of their roads.
Ie, before Lara 'briefly' stole the show in the 90s or even was anybody, Tendulkar was easily the foremost of the batsmen barring the absolute veterans.
In case like this, i dont think there could've been any justification for holding back tendulkar more than a year or two at most from international cricket.
I think people often forget the context of a particular event as time passes by and increasingly evaluate viewpoints by today's perspective. Australia back then was not as averse to giving debuts to young players.
