It’s understood the Ryder Cup legend and twice British Open winner met the Dublin players as a group for a motivational session earlier this year.
It’s not the first time the former Ballyboden St Enda’s player, whose father played in two All-Ireland finals with Cork, has spoken to Dublin teams.
He addressed the Dublin footballers at Parnell Park a decade ago when Tommy Lyons was in charge, a session that was described as ‘phenomenal’.
And his latest motivational talk clearly did the trick as Dublin enjoyed a stunning 2013 season with Allianz League, Leinster and All-Ireland titles all secured.
Harrington is renowned for giving passionate pep talks to various teams and individuals and was credited with inspiring Ireland’s Grand Slam rugby success of 2009.
“He is an intense guy when he gets going,” revealed a Dublin player.
“He’s a very deep-thinking guy and it all came out when he was speaking with us. I know personally I took a lot from the talk.”
All-Ireland-winning manager Jim Gavin has not spoken about the meeting or the reasons behind it.
Harrington was a promising footballer himself and marked future Dubs star Dessie Farrell in a colleges final for Coláiste Eanna at Croke Park in 1989.
His long-time fitness advisor Liam Hennessy revealed in a recent book about the golfer how he becomes so passionate when giving motivational talks.
“He just loves the opportunity to stand up and describe and talk about the game,” said Hennessy. “Because he goes so much into it and because he’s so passionate about it, it sends the little red lights flashing on the [heart rate] monitoring systems that we use with him. It’s like, hold on this is more stressful than competing in 30 degrees out in tournaments, for a Major or whatever.”
