Problems is not leaving Bangalore challengers

On ipl the most defeated team is banglore challengers. What may be the main reasons for that. Now i have figured out some reasons for their defeat. 1) They have no good starts. 2) They have good batting but orders but not utilised on proper way. 3) Of some poor feilding. These are the reasons which i can bring out of this team. If some body knows more please write down on comments.
