See.. if IPL 2020 happens, then it needs to start within the next few months. Because we have IPL 2021 starting in March 2021. So in case they schedule a tournament during October or November this year, then there will be a lot of viewer fatigue and the TV revenues will go down massively for the next year's edition. For the BCCI, the best thing to do is to call off this years tournament. They can make it up, by organizing a larger tournament next year. For example, they can add two new teams and make it a 10-team tournament.
On another topic which is related to bilateral series, BCCI should do some brainstorming in this free time and try to work on some Tri or Quad series for ODI and T-20, instead of bilateral series.
