Wales interim head coach Rob Howley expressed his frustration and disappointment after his side's 30-22 defeat against Ireland.
Ireland stormed into a 30-3 lead before Wales responded thanks to three second-half tries from Alex Cuthbert, Leigh Halfpenny and Craig Mitchell to narrow the gap to just eight points.
"It is frustrating and disappointing. With the way we started we allowed Ireland a foothold," said Howley.
"The key in any international game is territory and possession and we came second by a very long way.
"Ireland's kicking game, combined with our lack of accuracy at the contact area, allowed them field position, the pressure.
We were disappointed to lose another try in the first two minutes of the second half, but to come back from 30 points to three down to where we were... I think it is a silly question to ask about players buying in.
"It reminded me of the game against Scotland here a few years ago (where Wales scored 17 points in the final few minutes to snatch a remarkable win).
"We probably left four tries out there. We had two situations where we did not finish off two against ones and there were a couple of poor decisions in their 22. But the players showed a lot of character, which you want to see as a coach.
"It's a shame we couldn't score a fraction earlier in the second half. If we had I think that game could have had a different ending.
"On the other hand, in the second half we played a lot of good rugby, had a good impact off the bench and scored three tries. But in that first 20 minutes we need to focus. We spoke all week about starting well and we didn't."
