Galway used a second half nobody knew they had in ‘em on Saturday to edge dynastic Dublin, 0-17 0-16, in the All-Ireland football quarterfinals before about 50,000 fans at Croke Park. Galway hadn’t beaten host Dublin head-to-head in the annual national championship tournament since 1934. And Dublin, the most experienced and decorated squad in the land, had won seven of the last nine Sam Maguire Cups—including an unprecedented six in a row from 2015 to 2020—and was expected to cruise to yet another title this season.
