The only guy i feel is honest, competent or you can say loyal to Pakistan Cricket is Imran. Imran has the education, the personality, the respect to run PCB in a proper way. However, he is in politics and wants to go after the whole country itself and not just PCB.
The whole issue i guess, as i understand it so far is a mixture of things. Its not really one problem. The problem trickles down from the President nominating a favorite person as the chairman of the PCB and then there are no checks and balances on his authority. He is more or less the king of cricket. Even the selection committee can't do anything if the PCB chairman says a certain player shouldn't be selected or should be selected.
So, no 1. the nomination has to be changed to election, no 2. a proper constitution has to be developed which will give certain rights to different bodies with in the board. I.e. the chief selector has the main say in selecting players and not the PCB chairman. Similarly, equal representation has to be given to all the provinces and there local bodies in the PCB. Players should be selected on merit and domestic performance. These can be done if a properly educated person especially in the managerial field comes who has some international or FC level cricket behind him as an asset but his main area must be management. Similarly selectors have to be proper cricketers, coaches etc.
It doesn't matter who comes as a PCB chairman at this point. The system in which PCB is running at the moment, i only see Imran changing that around because he commands the respect and has the brains which can turn things around in PCB but what happens when he leaves and is done..the next guy walks in to take over all authority, i can trust Imran with such authority but not other random people.... So, at the end of the day what really needs a change is our overall socio-political culture and it will trickle down to cricket automatically.
I don't see bringing in former players other then Imran would make a difference, even Imran's presence will bring temporary change, because anyone coming in after, will stick to the status quo and just change the face of the PCB a bit not the core.
