As I've previously pointed out, the biggest lesson any team can learn from India's recent triumph is the value of A team cricket and FC cricket. But especially A team cricket.
Pakistan have never in the past, and certainly won't in the near future invest money in A team tours that are necessary for young guys to evolve from domestic cricketers to international stars.
Furthermore, any top quality team is judged most of all by its bench strength. Pakistan doesn't have any bench strength to speak of and many issues in the first team like mediocre, underperforming openers who would be sitting ducks on any wicket in SENA or the fact that we don't have a third seamer who can pair up with Hasan Ali and Shaheen and actually be successful in a country like Australia.
Abbas would be a candidate but he is currently out of the team and its a long road back for him. And other than him there's no one out there who wouldn't get taken to the cleaners in SENA.
