Is there a particular reason Smith is in the side? While I'm sure his 8 runs and not bowling were essential to the aussie cause, what has he ever done?
SPD Smith (31 ODIs)
351 runs @ 21.94 (HS 46no, SR 86.24)
22 wkts @ 33.50 (BB 3/33, SR 38.41, ER 5.23)
Nothing special there, not a fifty in sight and his bowling has been very ordinary, and indeed not even used in the past two matches. He's bowled 24 times in ODIs.
0 wkts : x10
1 wkt : x7
2 wkts : x6
3 wkts : x1
So 42% of the time he doesn't take a wicket, in fairness he doesn't always bowl that many overs with an average of nearly six overs per ODI he actually bowls in.
Bowls 01-08 : 9 wkts @ 33.44
Bowls 09-16 : 9 wkts @ 22.89
Bowls 17-24 : 4 wkts @ 57.50
That middle spell looks quite handy, but that was eight wickets in one series against England down under where he took 8/138 in the series. He took out only England batsmen and Prior, no rabbits, and including Bell twice and Morgan twice who respectively averaged 22.00 and 17.67 in the series. Hussey took seven wickets in the series, England were just too poor for words with only one batsman making more than 200 runs in the (seven match) series. England's joint best bowlers took seven wickets, same number as Hussey.
Over half of his innings have come against England, 11 innings, 203 runs @ 25.38. Surprisingly what few innings he has had against non-Test playing nations plus Bangladesh and Zimbabwe have produced just 34 runs @ 11.33. Equally his bowling record against the same sides is 3 wkts @ 60.00
Does that make his record against the relative 'big guns' look impressive?
vs ENG/IND/NZ/PAK/SAF/SL/WIN
317 runs @ 24.39
19 wkts @ 29.32
Still a poor man's all-rounder, you might just about pick him as a spinner for his batting ability, but I would have thought Australia strong enough in batting not to need him.
