What changes do the Indian cricket team need to undergo in order to become a winning team once again?

I think that they should drop the slow useless batsmen like Sehwag, Kaif, etc and they should either bring back an old opener like Ganguly or something or bring in an aggressive opener. Also, they should keep the bowlers like Zaheer Khan who are in good form. The best change they could probably make is the sacking of Greg Chappell plus Dravid's leave as captain. He just doesn't have what it takes to be captain of India. Oh, and Dhoni should be #3 or something so that next time, he can save India after the 10th over, not the 30th over.
