I think if we see only the second half of the tournament Delhi didn't really deserved the title in any way. They performed pretty badly in second half. There were other teams who performed much better. I expected SRH to reach the finals as they played much better in the later half. All on all I felt matches in the later half of the IPL much less thrilling.
Even though i missed the early part of the IPL i watched the matches this month and DC was not in a position to get to the final but they played a good match against SRH which none expected because if you compare their performance SRH was consistent while DC was really struggling and they were able to perform well on that day but against MI they accepted defeat from the start.
