Regarding Greg, I think he was sidelined while team selection. He wanted youth, but he had to go with the original team of two three year ago.
Dravid is not much aggresive as Saurav (based on the look in TV)but he is a good player and thinker. He backed Sehwag, who only put some resistance in last two matches.
Stratergy of putting Sachin in middle to provide strengh in middle order had to changed after return of Yuvraj and Ganguly.
Seeing the performance of Ganguly, I think he is best suit for Middle order.
To move ahead ground fielding, fitness level, enthusiasm in field and proper batting stretergy is must. We had superb batsman on paper, but unable to unite and extract them. It will not be wrong if said, They all are playing for themselves now the way Saurav, Yuvraj, Sachin batted.
