I agree to a certain extent. I am not sure about Dhoni riding on luck.....he does have talent, no doubt about that.
But as you say Ganguly or VVS can be good choices. VVS though seems to be having a poor run at the domestic circuit....so not sure whether the selectors will consider him!
Playing in Aus can be real tough and a seasoned campainger like Ganguly would be a better bet I think. Pawar I am sure will not let that happen though!
Ultimately, Indian cricket is mostly about politics and money...not much on merit/experience!
