Rohit Sharma demanded to tone down the criticism directed at wicket-keeper Rishabh Pant after the latter's error in judgment cost India a review and in hindsight potentially the match.
In the tenth over of Bangladesh's chase, Yuzvendra Chahal trapped Mushfiqur Rahim plumb in front of the stumps but India did not challenge the on-field umpire's not-out verdict.
Two deliveries later, a vociferous appeal from Pant for a caught-behind of Soumya Sarkar caused Rohit to ask for a review only for the replays to show there was a wide gap between bat and ball.
Buoyed by the reprieve, Mushfiqur built on the strong foundation and made an unbeaten 43-ball 60 to seal Bangladesh's maiden win over India in the shortest format.
"Of course, Rishabh is young and he will need time to understand," Rohit told reporters following the match.
"It's too soon to judge whether he can make those decisions. Plus, the bowlers as well. It's a combination when the captain is not in the right position to make that decision."
Pant's poor DRS calls coupled with his ordinary batting performance resulted in fans passing seething comments on the young cricketer.
With Pant touted as MS Dhoni's successor, Rohit defended the 22-year-old and shed light on the difficulties involved in making spontaneous decisions related to DRS.
"When you are not in the right position [as a fielder], you have to trust your bowler and the wicket-keeper. Based on that, you have to make that decision, whichever format you play," he added.
India found it hard to score runs on a tough pitch in pollution-hit New Delhi and managed 148-6 in their 20 overs.
Rohit, the stand-in captain in the absence of Virat Kohli, believed India still had enough on the board had they not erred in holding onto certain chances in the field.
"We would have defended 148 if we were smart on the field. A couple of decisions, we did not get it right on the field, and that went against us. That's where we lacked in decision-making.
"It was a good, fighting total, but when you defend such a total, you need to keep taking wickets. But they had good partnerships, and that was the turning point."
