Weird post. Most cricket fans in the world are in India so how that lessens the relevance of the IPL is beyond me.What metric is this based on? Having millions-billions of Indian followers on Social media? Most cricket fans in the other top nations like Australia, England, South Africa and NZ don't care about the IPL any more. It was cool when it started but it lost its aura years ago. The relevance of the IPL is highly skewed by the population of India.
Also South Africa & NZ aren't top cricket nations when it comes to financial importance. Not a whole lot of cricket fans in either country. Hence why most casual cricket fans wouldn't know the names of their T20 comps.
