I think PSL has been on a successful track and every year the tournament gains more popularity. However, the Pakistan cricket board should focus on getting more International players in PSL. We have seen limited numbers of International players and that is the reason PSL lack behind the IPL.
If PCB can manage to attract more International players, I am sure the league will become even more popular, however, they need to have enough money in order to do so.
There is no doubt every year things going into positive way for the PCB and PSL because viewership is increasing with media rights are also getting good increase but keep one thing in mind PSL or any other league never been going to compete with IPL because this is having one off the biggest cricket market in the world like EPL of England they are having much better viewership and other things which are helping them for ruling into cricket world with this all every league having its own benefits and negative points.
So, I have feeling like comparing them with each other is never been ideal things but still good now we have few good leagues which are helping cricket and players for having good experience and money as well in next few years if we have things better in this region then surely we will have good increase in revenue and other aspects of these few leagues which are currently small and have not enough fan base as well.
Bringing International players is not in PCB hand because it's their own choice which is not in control of anyone but still we have the good number of players those are enjoying here and many after giving their best here joining IPL on high prices as well.
