Summary: Dublin and Kerry meet in the second All-Ireland semi-final this weekend, and the marquee rivalry in the GAA has managed to survive 70 years of almost uninterrupted Kerry dominance. We discuss with Kerry legend Darragh O Se and the Irish Times’ Malachy Clerkin. US Murph tells us about the NFL’s control over the media, and why America's most popular sport isn't too big to fail, while acclaimed author and journalist David Epstein explains why Darragh O Se was always going to be a good footballer, and Daithi O Se was never going to cut it. His book “The Sports Gene” investigates why sports stars are as good as they are. All this plus Cluxton's kick-outs, cankles, an Andy Townsend Tactics Truck Pierce Brosnan Emigrant Shout Out (ATTT PBESO) and will Ireland ever win the Olympic marathon.
