More than discovering stars, the PSL's main job is to develop the undercooked domestic players. PSL teams conduct trials, but it will be a miracle if even one of these trials unearth a international cricketer who has not had the opportunity to play professional cricket yet.

They are getting a taste of what it is like to play against big crowds, in high pressure matches and against international quality opposition. We have seen the influence of the IPL on the Indian players. When you are playing against the best players in the world in front of packed stadiums before making your international debut, the jump from domestic cricket to international cricket becomes insignificant.
Most of our youngsters post PSL have taken to international cricket like fish to water, and none of them were discovered by the PSL. It has only accelerated and enhanced their development as cricketers.
