I would agree with Hmarka 100% on this. I think that India is probably at the moment the strongest batting side in the world in my opinion. I think with the likes of Sehwag, Tendulkar, Ghambir, Dravid. India has a deep batting lineup that is tough to beat, however there bowling attack has weakened substantially since the obvious leave of the great Anil Kumble. Now Harbajan was supposed to be the man to come out of the shadows of Kumble and really spin matches to India's favour.
Now the problem is that he has shown that he is not the same bowler that he was and that's why he must be taken out. Now the question is how do you find the next spinner to replace him, I think you don't need a GREAT spinner like Kumble you just need a spinner who willl be useful and can be very dangerous. A spinner like Nathan Hauritz, a guy who can take very crucial wickets like he did against Pakistan and a guy who won't go for too many runs at a time.
India has to test out a few spinners, I think the obvious choice is Ojha because he is like Gazza said he is very talented but they must test out a couple until they can find the right spinner.
