Problem with KKR

In the last season of IPL, Kolkata Knight Riders took a very good start in beggining but were unable to continue it later. This season, they've improved a lot and have won just 1 match till now. There are several reasons.
1) 4 captains of one team: Before the starting of season 2, the Kolkata team was in focus as the coach of the team was trying to use the mathod of 4 captains! This led to decrease in support of Kolkata Audience.
2) No Dada, just Macculum: When team reached SA, the post of captaincy was replaced by Macculum on place of S. Ganguly.
3) Good bye of SRK: Due to unsuccessfulness of the team, SRK returned India. He also said that he'll go back to SA only when his team will win a match.
What do you think? Be free to post any comments. Was SRK right in taking the decision of returning India? Did the change in captaincy is the cause of unsuccessfulness of team? Tell us what you think. Waiting for your answers.
