I really don't see how this can happen with the cases increasing in India daily while in Australia the cases remain under control for now. It will be sad if we have to wait this long just to see the T20 world cup but as I said before in here, it all comes down to money and power and the BCCI seem to have both.
What does money power to do in a situation like this, since the T20 world cup is hosted by Australia and the situation there is better and hence there would not be any resistance in going with the series. If they wanted to conduct the IPL then there is no way they can conduct with the situation is not favorable and money power cannot do everything during a pandemic.
Its always about the money my friend no matter what, that is why the world is starting to open up even though the cases are still very high daily because they need to get the economy going again and the same is for sports. We shall see what happens in the coming weeks but I do hope that the T20 world cup goes ahead as planned and not postponed for a year.
