I am sure PAK management is not aware of whom are their best players or what is their best combination. I have seen only 2.5 matches so far, but already can say
1. Batting wise 4, 5 & 6 are far better than 1, 2 & 3
2. Zeeshan is far better captain than Rafique. Rafique has a decent domestic record, but I don't think he deserves a starting spot, they made him captain. Only meaningful match that PAK won so far, Rafique wasn't part of the team.
3. Bowling combination is wrong, PAK should have gone with 3 pacers, particularly when one of the pacers can make the team simply as a batsman. Besides, I don't think Gul is the best pacer in the team. In fact, if he is Pakistan's best U19 prospect, then future is not that bright.
