Tadhg Beirne denied that Ireland failed to match Wales' desire as they fell to a comprehensive 25-7 defeat in Cardiff.
With that, Warren Gatland's men claimed the Grand Slam, leaving Ireland to lick their wounds with the players returning to provincial duty for the next five months before a friendly match against Italy on 10 August.
"It certainly wasn't the case for me anyway and I can definitely speak for everyone in there," Six Nations debutant Beirne told RTE Sport.
"Everyone goes out there to win and everyone was hungry for this especially knowing it was [Rory] Besty's last game in the Six Nations and we spoke about that all week.
"We were eager to get out there and put in a performance. Unfortunately, it didn't work out today."
Joe Schmidt's men fell behind to an early Hadleigh Parkes try and failed to cause their hosts any significant problems.
"Obviously an not ideal [start]," said Beirne, who played with the Scarlets for two years.
"We wanted to go after them a bit and they put a lot of pressure on us from the kick off and they executed the try very well."
Fellow Munster forward Dave Kilcoyne, who came on as a 59-minute replacement, agreed that they faced an uphill battle after the early score.
"They started the game very well. It was a tough game to go chasing in those conditions and I think Wales started that little bit better, credit to them.
They were playing in front of their home crowd, they were playing for the Grand Slam. I'm not using that as an excuse why we didn't perform."
In the aftermath of the defeat to England, which Schmidt claimed was worse than the loss in Wales, the head coach said he sensed all was not right in the camp.
Asked the same yesterday, he would just say that an illness in the camp disrupted their preparations.
"[We had] A few guys struggling with a bug. They were isolated and you lose a bit of continuity," he said.
