I don't think this "good change" thing is happening any time soon. There's a hell lot of difference in the domestic structure of Indian cricket and Pakistan cricket, and after observing today's match between India and Pakistan, it's clear that Pakistan will not be able to have a good team in upcoming years. Still, PCB's new management and their roadmap are all flawed; it's time to copy/paste the structures of either Australia or England.
I highly doubt that merely copy/paste of any structure going to help Pakistani cause here, unless PCB recruit some sort of honest individuals, they no need to be 100% honest in that case but they should put country's interest first. At least avoid petty politics and select players on merit only, not because he's someone's nephew etc.
