Oh yeah. There's also a game, officially called the Emerald Isle Classic, to be played at Ireland's gleaming new Aviva Stadium, a 50,000-seat venue normally home to Ireland's national soccer and rugby teams, which has just experienced the first ticket sellout in its two-year existence.
Both coaches said it's been a challenge to keep their hyped-up players focused on the importance of the game - and sufficiently well rested following what, for most athletes, was their first trans-Atlantic flight - since arriving here Thursday at the crack of dawn.
"We feel very privileged and very blessed to be here along with Notre Dame. There's not too many teams that get this kind of opportunity," Navy coach Ken Niumatalolo said. "But other than that, we've got to remember we're playing a very good football team, so we'd better get ready."
Navy is officially the home team, but that's tough to discern given the heavy Irish Catholic bias in favor of Notre Dame. Sightings of tourists and locals in Fighting Irish regalia easily outnumber Midshipmen supporters 20 to 1.
"Obviously the Notre Dame brand is pretty strong out here, so although we're away from the United States we feel pretty comfortable here," said Notre Dame coach Brian Kelly, who traces his Irish roots to great-grandfather Eugene.
