I am not sure if the selectors are allowed to bring in players from outside of the squad, but if they could then my team would be:
1. Gilchrist
2. Hayden
3. Ponting
4. Katich
5. Clarke
6. Symonds
7. Hussey
8. Harvey
9. Lee
10. Gillespie
11. Williams
With Hogg out of form and especially against the Indians, I wouldn't use him in the finals series, although I do think that Twizzle's point about the Indians having not seen him is a good one.
Also I think that In Timbo's team, there was perhaps one too many bowlers with Gillespie, Lee, Kasprowicz, Hogg, Harvey and Symonds- not to mention Katich and Clarke. Also, i was surprised at the omission of Williams, who's been on fire in this series, and leading the wicket-taking list.
Having Hussey in the team would add depth to the batting lineup, and he could serve the same purpose as Bevan did with the bat. Also, he is a handy medium-pacer.
I believe that Harvey has been a bit hard-done by this series by the fans. He has made a few decent knocks at the end of an innings averaging 17.4 this series at almost a run a ball, and has often come in with limited oppurtunities, whilst his bowling performances have been moderate, despite having to bowl to the Indian middle order batsmen at the death more than once. Personally I believe that he could handle himself in the team as just a bowler.
Anyway, this is just my opinion and feel free to lodge your own about my team.
