This doesn't give him any right to talk rubbish all the time, he's not the president of some local club but representing a major country in the cricketing world.
Likes of Lalit Modi, Srinivanas minted a shitload amount of money for BCCI. Do we neglect their wrongdoings? No and rightly so.
Lalit and Srinivasan made money from an already established market. Rameez's job was more difficult. And Lalit and Srinivasan are hated by the fans because of their nepotism, bias and corrupt practices. None of this is true for Rameez.
He's also a product of nepotism and was born with a silver spoon. Got a preference from start be it school, college, club and domestic cricket due to his father and brother's connection. He himself mentioned this many times on the record, proudly.
Rameez's duty is to take care of the administration and the finances. If the batsmen fail to score runs, I don't know what he can do about it. Maybe he can suggest a few changes in the batting order, and that is it. Still I am against a large scale reorganization, because the batsmen showed a lot of promise in Australia. There were indications that they are no longer heavily dependent on Babar Azam. And also, youngsters such as Mohammad Haris were scoring crucial runs.
That's the main point. He's the administrator so he should act responsibly and not indulge in a street fight by sending a legal notice to former cricketers or experts.
