PRO FOOTBALL—Like the Giants, who got off the schneid by defeating previously unbeaten Tampa Bay 17-14 (page 34), Baltimore won for the first time, not only for the season but since last Nov. 12, by upending the Jets 10-8. Colt Cornerback Dwight Harrison saved the game by batting down New York Quarterback Richard Todd's fourth-down pass on the goal line with 3:08 left on the clock. Cincinnati and San Francisco are still searching for their first triumphs. The Bengals lost 10-7 to Kansas City, and the 49ers were beaten by Seattle. Seahawk Linebacker Sammy Green returned an interception 91 yards for a touchdown, and Jim Zorn connected on nine of his first 10 passes as Seattle jumped out to a 21-7 lead and then coasted to a 35-24 win. Pittsburgh built up a 27-0 lead in a 51-35 rout of the Browns that featured the throwing of Cleveland Quarterback Brian Sipe and the running of the Steeler backs. Sipe threw for five TDs and a career-high 351 yards, while Pittsburgh picked up a club-record 361 yards on the ground. Franco Harris, who had touchdown runs of 71 and 25 yards, finished with 153 yards on 19 carries. The Chicago-Buffalo game pitted the AFC's most successful passer against the NFC's most productive rusher, and the runner came out on top. Bear Walter Pay-ton carried the ball 39 times for 155 yards and the game's only score. Joe Ferguson of the Bills, who had thrown for more than 250 yards in each of his four previous outings, wound up with just five completions for 50 yards in his team's 7-0 loss. Denver beat San Diego in another 7-0 game. Quarterback Norris Weese scored on a three-yard run after Safety Bill Thompson had raced 26 yards to the Charger 11-yard line with a recovered fumble. Philadelphia bumped Washington out of its share of first place in the NFC East with a 28-17 win over the Skins. Wilbert Montgomery rambled 127 yards on 22 carries and scored all four Eagle TDs. Philadelphia now shares the lead in the division with Dallas, which beat Minnesota 36-20 behind Tony Dorsett, who galloped for 145 yards and three touchdowns on 21 carries. A fake punt and an interception with 6:36 to play set up one-and six-yard scoring runs for Wayne Morris and lifted St. Louis to a 24-17 upset of Houston. The Cardinals' Jim Hart was intercepted three times in the first half but ended up completing 23 of 38 for 253 yards. Los Angeles picked off five Archie Manning passes en route to a 35-17 victory over New Orleans, and Green Bay did the same to New England's quarterbacks in a 27-14 win on Monday night. On Sunday, though, the Pack saw its passer victimized in Atlanta. The Falcons sacked Quarterback David Whitehurst eight times, once for a safety, and Atlanta's Tim Mazzetti booted 23-, 48- and 42-yard field goals. Final score: Atlanta 25, Packers 7. The Patriots, meanwhile, narrowly escaped being upset again. When a 14-0 lead turned into a 17-14 third-period deficit, Tom Owen replaced the ineffective Steve Grogan at quarterback and rallied the Pats to a 24-17 victory.
