2. Mumbai Indians
They were the defending champions in 2014 but they had a disastrous campaign in the UAE. Slow starters Mumbai Indians (MI) lost all their 5 league matches in UAE. They were sitting at the bottom of the table after the first phase of IPL.
However, once they returned to India they turned everything around in style. Mumbai won almost every match and remarkably qualified for the playoffs. Their dream run was stopped by CSK in IPL 2014 and they were knocked out of the competition in the playoffs.
