Familiar Rivalries and Any Team's Chance in All-Ireland Football Quarterfinals

All-Ireland football quarter-final weekend features eight teams from across Ireland with no clear favorite to advance.
Kerry and Tyrone are facing off, with Kerry currently leading, while Armagh and Monaghan also play today.
Kerry, the defending All-Ireland champions, may underestimate Tyrone, who beat them two years ago.
Armagh and Monaghan have had ups and downs but are poised to advance.
Derry and Cork will battle at midfield, while Dublin and Mayo, familiar rivals, meet again in a match too close to call.
