True. And also this will not give them enough time to bowl as well. Its known that spinners need longer spells to bowl and get wickets. If you have four of them, then it is less than likely that all will enjoy this.
True, actually there is some differences between Dhoni and Sehwag/Gambhir. But it was not so much in open till we were doing good. But with the losses these are coming in all open and will be further dent the performance. Form wise they both should have been dropped but unfortunately we don't have a ready replacement.
