Mayo boss James Horan believes his side made too many basic errors in their 2-12 to 1-14 All-Ireland defeat to Dublin.
Mayo's wait for a fourth All-Ireland title will enter a 63rd year next year after the Connacht champions suffered a seventh final defeat in a row.
Their defence was tremendous all day and keeper Robbie Hennelly made a number of telling saves but their offence couldn't muster the scores needed to win.
"We'd enough ball to win the game, we just made too many basic mistakes," Horan told RTE's Sunday Game.
"We turned over the ball to often and the ball didn't stick inside for us and Dublin were launching counter-attacks.
"Simple mistakes let us down. In the second half Dublin came with a surge and we were chasing then and our composure just left us a little bit.
"We kept plugging away and kept trying as hard as we could, we just couldn't get there."
Mayo had a lot of turnovers and probably edged the midfield battle but Horan was unhappy with Mayo's decision-making.
"We were in good positions and gave away the ball at times. That's killer in an All-Ireland final," he added
"I'm very proud of the guys and all the work they put in. It was a game we were in but we just couldn't get the scores.
"We have very good players and some guys were exceptional today. It's disappointing for us but we'll keep trying.
"Dublin deservedly won, we have to look at what we did wrong and what we can do better.
"As a unit we didn't do enough."
