I think you are referring to Ajantha Mendis. Yes, he's a waste of space specially against sub continent teams. He's not adapting. His mystery is gone, so he should try to develop a good off break.Just why is mendis still playing? Nobody seems to get out to him anymore....
Why throw them all against the wall at once, rather than introduce them one at a time and let them settle with at least some support from a senior bowler or two.... because it's good to know who can hack it and who can't. If Praveen and Zaheer pull hammies in the middle of the World Cup, you wouldn't want some of this crap having to open the bowling.
I don't disagree with the policy in total, just think that they've taken it too far.Can't argue with that. Just like Raina and Karthik were there for the other young batsman, Sree could have been there for the bowlers.
But that being said, they're hardly up against the strongest teams themselves. Sri Lanka have played their seconds, and perhaps the BCCI expected better from this Indian team against Zimbabwe.
This is more a failure of the personnel then the policy in my opinion. If anything, I reckon the policy has worked.
Vijay hasn't been much chop at international limited overs level as some expected, and so team India knows that too. Sharma on the other hand has been pretty good.
