Let's not be too hasty here. It is only the 1st test. The XI should be largely unchanged though I couldn't believe that Kaif was not included in the side on form. Ganguly is the one that needs to be dropped but that would lead to great instability in the side and they don't need that. Keep him for the series and if he doesn't perform get rid of him.
Agarkar's century will probably keep him in the side but the Turbanator needs to come in somewhere either for Kumble or Agarkar.
My 2nd test side would be:
Sehwag, Jaffer, Dravid, Tendulkar, Laxman, Ganguly, Ratra, Agarkar or Kumble, Singh, Khan, Nehra
It's not the end of the world. The same Indian fans that raved about the one day performances are sinking the slipper into the side for their test performances.
