Except a few Indian players most teams in the WPL are dependent on the performance of overseas players. India's talent pool in women cricket is saturated. I am sure the BCCI would work on this issue to make things more competitive. At the moment it is MI who are looking as the front runner to pick the trophy of WPL.
There is no surprise in the overdependence on foreign players. It was also inflated by the fact that some capped Indian players were out of form.
But at the same time, we can confidently say that this inaugural season will only help Indian women's cricket as far as the talent pool is concerned. Yes, it'll take some time to mature but things are going in the right direction.
