Sachin vs Ganguly

Of the many things which I could never understand one was why was Ganguly dropped from the one day squad against AUstralia. He was in quite a good form. He has proved his dedication and there are only few who doubt his abilities.
I am not a die hard Ganguly supporter but nevertheless the man has proved himself on multiple occasions.
And what was more bizarre was why was and is Sachin in the team. I dont remember any responsible innings in the recent past. I have seen him get out like I would get out if placed on that pitch in the first few balls he faces. He has completely lost it and should be given some "rest". I understand that everyone has a bad phase. But in conditions when u have to chase 317 a player of his caliber can stick around for first 15 overs. Or at least try to. Terribly disappointed.
Kudos to Dhoni thought. Very good to see him and Kumble fight.
