EAST RUTHERFORD, N.J. (AP) — Rookie Xavier McKinney intercepted Andy Dalton in the end zone with 1:15 remaining, lifting the New York Giants to the brink of an unprecedented, six-win playoff berth with a 23-19 victory over the Dallas Cowboys. New York’s postseason hopes hang on the Philadelphia Eagles, who play Washington on Sunday night. Washington would claim the NFC East with a win or tie. Otherwise, the Giants will take it for the first time since 2011. The Giants would be the first team to qualify for the playoffs with six victories in a 16-game regular season and the first to do so after starting 1-7.
