RCB doesn’t have any of these bowlers:
1) Fiery fast bowler to rip through the opponent batsmen (Steyn, Morkel, Malinga, etc)
2) Skillful bowler to bowl in the block-hole (Bravo, Faulkner, Johnson, etc)
3) Crafty Spin bowlers to tie down the batsmen & pick wickets (Narine, Mishra, Ashwin, etc)
Most of the other strong teams in the tournament seem to have at least 1 or 2 types of above bowlers. It is fine if a bowler has an off-day (as it happened to most other teams as well), but to fail in every match, and every bowler getting smacked is a huge worry for us.
However, RCB seem to marginally have one quality in their bowlers. i.e., bowl good length with the new ball, generate some movement and pick wickets which Vinay Kumar, Rampaul, Unadkat are good at. This is what RCB should exploit and pick more & more wickets in the first 6 to 10 overs. This is the only way they can put the opposition under pressure. (They did so in few earlier matches in this season particularly at home but seem to have lost their way a bit)
