Domestic cricket was always a concern for Pakistan. Previously it used to be dominated by the club sides, but then the PCB rightly moved to a province-based setup. The current setup has improved the quality a lot, although a lot of work still needs to be done. Asking some of the national team members to take part in the domestic matches, and telecasting some of the important matches on TV can be very helpful. Also, it will be a good idea to have some of these domestic teams to visit SENA nations once in a while, for friendly matches against county or Sheffield Shield teams.
These days only preference is given to T20 and Pakistan is not a different in this regard. On local TV, only T20 tournaments of domestic cricket are shown not ODI or test. PCB is not a small board and can afford to send his local teams to SENA to give exposure to domestic cricketers.
Only test format can produce genuine cricketers not T20 format. These days even test cricketers are selected from T20 leagues.
Although the matter is strange, it is true in some cases. Firstly Pakistan Cricket Board seems to me not very strong financially. And there are some reasons behind it. Especially their board cannot organize international series or tournaments for a long time. I think this is their main problem. If they are successful in managing some events in their home ground then it is possible to bring quick success in other areas as well. I think the more revenue they can earn from cricket they will ensure better cricket as well as able to find better cricketers.
