Is giving too much bowling to part-time bowlers the reason for India's defeat to Pakistan?

Indian strength is batting. I can't accept your statement. This is the final match between India and Pakistan. Pakistan cricketers think that they do better some thing than India. They succeeded. Pitch is for batting. Indian cricketers were failed to achieve the target. Sehwag failed in batting the important final match. Dhoni tried very well, but failed. India lost the cup.
