Nigel Adkins insisted it was a case of job done following a thrilling Good Friday victory over Crewe Alexandra at Bramall Lane.
Goals from Che Adams and Ryan Flynn put the Blades in charge, before efforts from David Fox and Harry Davis stunned the hosts, only for Billy Sharp to head home the winner from Louis Reed's cross three minutes from time.
And Adkins was determined to focus on the positives speaking in the aftermath of the success.
He remarked: "The first-half performance was exhilarating at times, if we had been ruthless in front of goal we would have had the game won before the break.
"We were right at and dominated. So let's focus on that, rather than negatives of the second-half.
"Yes, we gave away two poor goals and we need to defend much better, but at 2-2 we could have caved in and lost.
"But we didn't, with a lot of youngsters out there, we dug in and showed that grit and resilience required to grind out the victory we needed and you always know Billy (Sharp) will pop up with big goals.
"We needed three points, we got them, now we move on to the next challenge at Southend on Wednesday.
The Gaffer, who named five teenage Academy graduates on the bench against the Alex, concluded by praising the younger members of his squad.
He remarked: "The youngsters here have a real desire and hunger to learn and improve and although they will make mistakes they are out there in the thick of the action.
"The way Whiteman and Reed combined for the winning goal was superb and all these players will only get better the more they play.
"We now have a clear pathway for them and I am excited for the future."
