Rahane and Pujara are still far off - give them some time! Heck, Yuvi probably would have retired by the time Pujara will actually debut
I made a prediction a while back that when Dhoni is skipper, we'd see the three keepers in the starting XI. Patel, Karthik and Dhoni.
I'd like to see Dhoni drop keeping and take up part-time bowling. With some coaching and a longer run up, he should hit 85 MPH easily, what with those big arms. And all the secrets of reverse swing are available to him, so he should do very well.
And if he's bowling, then Karthik should keep, as I still feel he is the best keeper in India.
And my third prediction was Parthiv Patel returning as a batsman alone. He's been awesome in domestic cricket, and was excellent with the bat when he played for India.
But this is unlikely now. I'd still like to see this happen:
Sehwag
Gambhir
Patel
??? (Sharma/Raina/Badrinath/Uthappa/Tiwary/etc.)
Yuvi
Dhoni
Karthik
And 4 bowlers. Problem is, there are so many good bats, and we don't need a part-time bowler (Can always play 3 seamers and one spinner with Sehwag/Yuvi doing part time duties), so it is unlikely Karthik will return. And Patel isn't the only one doing great domestically, and the selectors don't seem to have much faith in him....
