I feel like you are blaming Kohli way too much here since there are lot of variables in IPL Cricket and he didn't expect some of his decisions to backfire, but it happens to the best of them.
Yes I am. He is the captain so blame will go to him obviously. This is what he said after post match interview:
It was quite surprising, we thought the game might finish in the 18th. A bit of pressure at the back end can confuse you, anything can happen in this game. Good performance by KXIP, we were not in the game tonight. [About AB batting at 6] We had a chat, a message from outside about left-right combination and we wanted to go with it because they had two leggies. Sometimes things don't come off. We're pretty happy with the decisions we took, but it didn't come off. Having 170 was a decent score. The idea was to let them [Dube and Sundar] to get their eye in. They bowled well. It's not a great ground for bowlers but that's not an excuse. We take pride in our bowling. tonight it didn't come off and we have to accept it and take responsibility. There's always something to learn to go back and understand. There was no conversation with Chahal to be honest. The only conversation was with the last ball, we wanted him to push it away. Credit to Nicholas.
So pretty sure that it was not bathroom break :-D
I do agree with you about Siraj though. How many more chances will Kohli give him?
How would you explain Chahal's over in the super over when Sundar had very going in other matches in super overs.
. 1 6 . 4 4 helped the batsmen to boost their confidence after having a good over just before that over from Morris. Kohli wanted to stop the rhythm but calling Chahal instead of Sundar was wrong.
Anyway, maybe I am indeed putting too much blame to Kohli, but he does make bad decision and losses matches. Isn't he the captain of Indian T20 team too? It will be interesting to see how he goes when Dhoni is not around.
