The act of Choking in run chases !!

I was watching this match a month ago, when Lanka was touring NZ and in one of the ODIs, NZ had to score 1 run in the last over for a win with 1 wicket in hand. Mahela called in the old, wily fox Jaya to bowl the last over and James Franklin, who was the NZ batsmen playing cameo did not see anything impossible, hoping that the number 11 Gillespie will score the single. Jaya fired in 5 delveries and all Gillespie could do was to poke here and there. The single was elusive and the initial smile in Franklin's face was turning to be a wrinkle before somehow Gillespie scored off the last ball. Bottomline, Jaya is used to bowling the last over and when cricket lovers like me could deduce such things, all the well paid gang that accompanies Indian team had no strategy for the last over.
Lanka batted first and even though they lost wickets regularly, Sangakkara who is now gaining reputation of a super solid performer anchored the Indian innings with healthy contribution from Dilshan and Maharuf. Dilshan, who was hopelessly out of form for months, must have been waiting for this dream chance to revive his fortunes and feast on the toothless Indian bowling.
The Lankan total was gettable but somehow India managed to snatch defeat from certain victory, when Dhoni failed to accelerate and Karthik got out at the wrong time. India tail, which has not won a single run chase for several years now (either India has been winning by a bucket or loosing by a bucket and tail was never tested or blamed) faced a difficult task. It is now immensely evident that Kumble can not put bat to ball in tight situations, against genuine pace bowlers like Malinga and when Kumble goofed ball after ball, the ask became too much for Dhoni to get against Jayasurya. But even here, Dhoni could have got it since 12 of 6 is not a big ask but such story board finishes happen in dreams and India trooped out wondering how they lost a match where they were ahead of balls required vs runs till the very end.
