Between 12th March and 16th May there have been like 60 IPL T20 games and 30 T20 WC games. Assuming fairly decent over rates, that results into roughly 350 hours of T20 cricket which is over 20% of the 1500-odd hours between the aforementioned dates. For a sport which some 7 nations in the world take seriously, that's investing too much time in it.
