PRO FOOTBALL—Super Bowl champion Oakland looked stronger than ever as it rolled over San Diego 24-0, limiting the high-powered Charger offense to just 121 yards. Quarterback Kenny Stabler, who led the NFL with 27 touchdown passes last season, got two more, completing 13 of 20 for 139 yards. New England had a tougher time than expected before putting away Kansas City 21-17. The Chiefs had taken a 14-0 lead before Darryl Stingley scored two touchdowns and Jess Phillips one. A 30-yard field goal by Joe Danelo with three seconds remaining enabled the Giants to upset Washington 20-17. The Giants had tied the game with 1:56 remaining on an eight-yard touchdown pass from Jerry Golsteyn to Tight End Gary Shirk. Chicago downed Detroit 30-20 as Steve Schubert scored on a 70-yard punt return in the second quarter to break a 7-7 tie. Walter Payton scored twice and rushed for 160 yards, including a 73-yard run, the longest of his pro career. Green Bay saw a 24-point first-half lead dwindle to four as New Orleans scored twice in the third period on two- and three-yard runs by Chuck Muncie and once more in the fourth. Final score: 24-20. Favored Cincinnati's explosive offense failed to explode and its defense was riddled by Quarterback Brian Sipe, who completed 15 of 22 passes for 198 yards in a 13-3 Cleveland victory. A strong Miami defense and a sore ankle held O. J. Simpson to 71 yards in 21 carries as the Dolphins beat Buffalo 13-0. Fullback Norm Bulaich ran 20 yards for a third-quarter touchdown set up when Norris Thomas recovered a Bills' fumble, one of seven in the game.

Ron Jaworski threw two touchdown passes and the Philadelphia defense allowed Tampa Bay only 152 yards of total offense as the Eagles beat the Buccaneers 13-3. Baltimore downed Seattle 29-14, a 10-yard touchdown run by Roosevelt Leaks in the second period putting the Colts ahead to stay. The Cardinals couldn't seem to do anything right as they lost to Denver 7-0 before 75,002, the largest crowd ever to watch a sporting event in Colorado. Minnesota hadn't lost a season opener in 13 years, Dallas in five. It took a sudden-death overtime to decide whose streak would be broken. It was the Vikings'—Roger Staubach running in from four yards out to give the Cowboys a 16-10 victory (page 18). Houston routed the Jets 20-0.

GOLF—The U.S. retained the Ryder Cup at the Royal Lytham and St. Annes Golf Club in England, beating the British-Irish team 12½-7½ despite a disappointing performance by Jack Nicklaus and a loss by Tom Watson to 20-year-old Nick Faldo.

HORSE RACING—FOREGO ($5.80) broke a three-race losing streak by winning the $175,000 Woodward Handicap at Belmont Park for the fourth straight time.

Elmendorf Farm's TEXT ($6.60), Marco Castaneda up, took the $121,900 Secretariat Stakes at Arlington Park by 3½ lengths over perennial runner-up Run Dusty Run. Text's time for the 1[1/16]-mile race, which was switched to the dirt because of the rain-soaked turf, was 1:42.
