Yes it's true that after came of Rameez Raja Pakistan is constantly recovering their position. However, to make the team completely successful, many behaviors must be changed. In particular, he should now plan on team management, otherwise Pakistan's batting side will start to disappear again if this continues as Pakistan's batting side has started to weaken.
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.
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.
