That's cuz most people watch cricket in English language in Karnataka.
This is the first time I am watching IPL too because I am desperate for cricket after such a long break and Kannada commentary is unbearable. I went and added English version afterwards.
They should bring more experienced cricketers like Rahul Dravid or Anil Kumble or even someone like Harsha Bhogle in Kannada to make it more interesting.
