1> Attain stability in batting order.Experiments can't be done on regular intervals.
2> Sehwag is a batsman and should add consistency to his batting.Its not like getting 100 in one match and scoring 20's in next 10 match.
3> Pathan is a bowler first and with his pace should be opted as a 2nd change bowler rather than opening.
4> Get a quality spinner who can spin ball a good way coz our part time spinners like Sehwag,Mongia and Yuvraj are turning the ball more than Harbhajan.
5> Raina is good choice for middle overs, as he can twitch ones and twos but not for dead overs where one needs to hit fence.
6> Finally teach our bowler to bowl a proper channel ie in and around off stump and the use of yorkers in dead overs.
