The first game couldn't separate them and just one point kept them apart today but again Mayo must take refuge in the House of Pain.
Cillian O'Connor whose place kicking was flawless throughout the game was presented with the opportunity to level the game in the final seconds of added time and force the game into injury time.
But the assignment was just beyond his powers and he just couldn't steer it over. It ressurcted memories of Waterford's Pauric Mahony whose last second free against Kilkenny in the All-Ireland semi-final didn't reached the desired destination either.
The image of Diarmuid O'Connor crouched beneath the collar of his jersey sobbing uncontrolably is not the ending he or his brother deserved but the winning margins favoured Dublin today.
GAA followers are posting their tributes to O'Connor and it's testament to the community spirit of the sport that they are honouring his contribution to this epic game.
