But there was a more fun to be had on this occasion as stars of Sunday's game, including Paul Flynn and James McCarthy, were joined by some familiar faces.
Former All-Star Alan Brogan, ex-Derry player Joe Brolly, selector Mick Deegan and Dublin County Board chief John Costello donned their football boots for the special charity match in aid of charity Goal.
And while it has been years since Brolly has taken to the field, the lads did not take pity on him.
Super-sub Kevin McManamon made sure to get a tackle in on the outspoken GAA critic and the team still had plenty of energy despite their week of celebrations.
The black eye defender Philly McMahon sustained in Sunday's victory had even shrunk a bit.
After the mock game, which lasted 20 minutes, players mixed with the young fans who had turned out at Parnell Park.
After handing his number 10 jersey to Dublin girl Amy McNally, Paul Flynn signed tops and posed for photos, while fellow forward Ciaran Kilkenny chatted to Raheny native Evan Brady Browne (6).
That's a lot more civilised than the tackle on poor old Brolly.
