The thing is, even if someone fleet of foot like Nasir was sent up the order it would have failed as his running partner, Tamim, would not have been able to keep up and/or would have continued to refuse doubles and triples. (This in turn would put off Nasir who would probably get out trying to force a boundary)
I think sending Mushfiq and then Zia would have been good to continue with the momentum. Riyad has been in form but the ODI series required innings of a completely different pace than what was required in the T20i.
If we would have been able to crack a hundred within the first 10 overs - very much on after 43/0 after 3 overs - it would have eased the pressure on Nasir/Riyad/Mominul to score the remaining 97 later on, even if there was a collapse of wickets.
