Reason behind sudden resurgence of KXIP

The way Kings XI are now playing indicates that it was Sangakara who underperformed and under captained the team.

Or may be Preity Zinta's dip in the holy Ganges is doin the trick for her men who are more eager to get a jaddu ki jhappi than play their real self on the game.

Perhaps a jadu ki jhappi to Sanga would have done the trick.  Something similar(Sreesanth's crying act) antics would have been done by him in the dressing room to get the jhappi and once he had got it, he would have realized like a Bollywood hero that he is the captain and must perform.

So he did, but a bit late, the train to semis was already missed.
