Not really, just coming up with an idea is something anybody can do, even a lay person on the street. Executing is the difference.
Zaka Ashraf abandoned the PSL because back in 2012 he was told that we were not getting high quality international players in the draft, it is a huge financial risk, hosting it outside Pakistan will not be profitable and it will only work in Pakistan, we don't have the expertise to do it. He had even launched the PSL and had spent millions on the project before deciding to abandon it.
All I know about Nasim Ashraf is that he drained the PCB coffers big time from 2006 to 2008, hired and fired people at will, ran like a chicken once Musharraf was forced to resign and has never set foot in Pakistan still. There were so many NAB inquiries against him. A fake Insurance contract for an abandoned Pakistan Australia series, the costly acquisition of a Bio Mechanics Machine at the NCA which was never used. Check out all the available reports. The PCB was in a healthy financial state when he took charge in 2006 and was in a mess when he left and even worse is the fact that Pakistan hosted the Asia Cup in 2008 so it is inexcusable to be in such a poor financial position. He even gave up Pakistan's Dues from the 1996 World Cup from the BCCI just to please them.
Good riddance. Sethi is on a different level compared to that crook.
