Kieran Kingston has not forgotten Cork's disappointing Munster SHC exit at hands of Waterford, but today's All-Ireland qualifier victory over Dublin went some way to righting the wrongs.
After allowing Waterford to rack up 1-28 with some degree of ease last weekend, the least the Cork manager required from his young team was more aggression and work ethic and he got that against a physical and difficult Dublin side.
"We were hugely, hugely disappointed with last week. Today does not take away from what we did last week and what we didn't do, but look, we got a reaction from the lads," Kingston told RTÉ's Saturday Sport.
"We saw a fight there during the week in training and they brought that to the table today in terms of attitude, intensity and workrate."
Cork will be drawn against Tipperary, Wexford or Clare in the second round open draw on Monday's Morning Ireland, but Kingston confirmed next weekend's game will come too soon for the Cadogan brothers, Alan and Eoin, or Darragh Fitzgibbon.
However, the Rebels boss will have more faith in his young charges after this display in Semple Stadium, with Robbie O'Flynn and Declan Dalton shining alongside more established team-mates like Mark Coleman, Seamus Harnedy and his own son Shane.
"We were playing against a really tough team, a big physical team, who are going to come at you, work hard and challenge you in the air, with runners coming through the middle.
"They hit you very hard and we had to be ready for that and I think our lads, albeit there were a lot of very young lads out there, they stood up well to it."
However, while he was pleased, Kingston knows that one swallow does not a summer, nor an autumn or winter, make.
"All it is is it gets us into the hat for Monday, we can't get carried away with one game," he said.
"We did not know where we were at last Saturday, because we had been away for eight months, today gives us a good sense, and Dublin had two games before they played us.
"We knew they were coming in hot so we knew it would be a tough physical battle, our lads stood up to it and it gave us a good sense of where we're at."
