Basically just selected based on the order of draft picks unless it was for balance reasons. 1. Mohammad Hafeez 2. Cheteshwar Pujara 3. Kumar Sangakkara 4. Younis Khan 5. Virat Kohli 6. Misbah-ul-Haq 7. Mahendra Dhoni 8. Ravichandran Ashwin 9. Zaheer Khan 10. Saeed Ajmal 11. Junaid Khan
Yeah Jadeja over Hafeez would be ideal but there's already one makeshift opener. Guess maybe Ojha for Ashwin, but it does weaken the batting.
Bring Jadeja in for Ashwin. Having enough bowling isn't an issue when your opening batsman is Hafeez.
Ashwin got picked before Jadeja though. Which hand someone bowled with seemed too petty a thing to go against the "order of selection" pseudo-rule.
