RCB looked great in the beginning of this season (it happens almost in every season). But they somehow lost their way. When things were good that was the time for us to experiment with the players, but we never did. We got stuck to players like RP Singh, Dilshan for way too long. Even trying Tiwari to open the innings should have been done after first few matches itself, by now he would have gained confidence.
I think RCB were too late to react to the situations. Look at RR, they are floating Watson in the batting order knowing that he is the key player for them. We should have done something like that really.
