BCCI has slowly and silently reducing the test footprint for the Indian team. Tests have become two test "series".BCCI needs to do a lot more on that front. They should incentivise cricketers to make test cricket their main format. I do think they are taking steps to address that. Let's see.
It's going to become a problem for various countries though as well. Except England and Australia who have their ashes trophies to think of to some extent.
BGT, ATT are good for now. But for how long, who knows. As the years go on, the newer fans could not even get into test cricket. Only follow IPL.
No need for BCCI to do more for tests. Let the free market determin things. Nothing should be forced. Market forces should determine things.
