India have immensely talented batsmen like robin uthappa, yuvraj singh, sanju samson,gautam gambhir, rayadu, not making the way into team due to too many batsmen already, hence non availability of slot.
Likewise pakistan have immensely talented bowlers like amir, asif, junaid, umar gul not making way into team due to ban or other reasons.
Just a fictitious thought, if we had players exchange programme it wud make a perfect team for each others, with pakistan importing some batsmen and india importing some bowlers.
