I didn't say Smith won't make it, but he is clearly not ready as a 21 year old, IMHO. His batting is scratchy, bowling is nude. Come back after a few years dominating in Shield & County cricket (not 10++ years like Hodge).So did Steve Waugh when he debuted. I'm not saying Smith should have been picked, but you can't say someone won't make it based on how they are at 21.
Not always anyway.
PS: he needs to figure out what his speciality is in the longer form of the game and if it is as an all-rounder, the genuinely good ones pretty much warrant his selection as a top 6 batsman OR a top 4 bowler, then be good at the other discipline.
eg: some allrounders I've seen play over the past 25 years (of course not an exhaustive list):
Top Tier or "genuinely great": Kallis, Imran, Kapil, Botham, Hadlee
Next Tier of "genuinely good": Vettori, Cairns, SPollock, Freddie
interesting that more bowling allrounders come to my mind and most of them are medium/quicks.
