Yea, I always got the impression Dhoni really didn't have that much faith in the bowlers in test matches, especially with all those flat pitches.
The Captain should be able to come up with plans, set fields, and ask the bowlers to bowl accordingly. And similarly, the bowlers should be able to follow through with the plans.
That's what Morkel and Steyn did so brilliantly, and to a lesser extent Harris and Kallis. They bowled to their plans when the pitch didn't suit them.
Ishant and Sree don't have that ability, atleast by the look of things. It may just be that they seem so wayward and without control because Dhoni is telling them to do they're own thing and they're bowling without patience looking for wickets.
But yea...we need bowlers who can bowl to a plan, consistently. Bhajji has sucked recently because his bowling has lost it's venom, but it could equally just be because he's bowling without a plan, so he can stay. Zak can stay too...but we need new bowlers. Or atleast, more consistent ones. Such a flogging is unacceptable.
Also brings up the question about what Kirsten is doing with the squad if the bowlers ran out of plans so soon. And the selectors, why why why why why WHY did they select Unadkat? Over Mithun and Munaf?
