PRO FOOTBALL—Buffalo, Detroit and San Francisco, three unexpected division leaders, remained unbeaten, but the Super Bowl-winning Steelers stumbled after six straight wins. The Bills, who lead the AFC East, defeated New Orleans 35-26 as Joe Ferguson threw for 295 yards and three touchdowns and rookie Joe Cribbs ran for two TDs. NFC Central-leading Detroit, seeking its first division title since 1957, dropped St. Louis to 0-3 with a 20-7 victory, in which the Lions' Billy Sims gained 95 yards to hold on to the league rushing lead, and the Cardinals' Jim Hart became the seventh NFL quarterback to pass for at least 30,000 career yards. San Francisco let Jets Quarterback Richard Todd build up some impressive passing statistics in the 49ers' 37-27 win over New York. Todd completed a record 42 passes—17 of them to Running Back Clark Gaines—good for 447 yards and three touchdowns. Nevertheless, the Jets are still winless, and San Francisco, which leads the NFC West, is off to its best start in 18 years. In the AFC Central, Pittsburgh and Houston share the lead. The defending champion Steelers turned the ball over six times in their 30-28 loss to Cincinnati, which got two fourth-quarter TD passes from Jack Thompson and a game-winning 21-yard field goal from Ian Sunter with 2:25 left. Pittsburgh had not lost since its penultimate 1979 regular-season game. Houston caught up to the Steelers by defeating Cleveland 16-7 on Monday night and Baltimore 21-16 on Sunday. Ken Stabler hit on 23 of 28 passes against the Browns, but it was the Oiler defense that connected with Colt Quarterback Bert Jones, sacking him five times and breaking his nose. Six interceptions and a fumble recovery by the San Diego defense in a 30-13 defeat of Denver kept the Chargers unbeaten and a game ahead of Oakland in the AFC West. Dan Fouts of the Chargers passed for 211 yards. The Raiders kept pace by beating the Redskins 24-21 before 45,163 fans, the smallest regular-season crowd in Oakland since 1975. In Anaheim, the Rams performed as they hadn't in two previous outings, scoring 37 second-quarter points in a 51-21 win over Green Bay. L.A. intercepted three passes by Lynn Dickey and two by Bill Troup, with rookie Johnnie Johnson running one back 99 yards for a touchdown and Ron Perry taking another 83 yards for a TD. The quarterbacks in New England's 37-31 victory at Seattle were able to confine their scoring passes to their teammates. The Seahawks' Jim Zorn threw for four TDs, compared to Patriot Steve Grogan's three, but Grogan's third one was a 16-yard game-winner to a leaping 6'7" Don Hasselbeck with 2:52 remaining. Elsewhere, Dallas beat Tampa Bay 28-17 as Danny White threw three touchdown passes for the first time in his NFL career; Minnesota held Walter Payton to only 39 yards rushing in its 34-14 victory over the Bears; Bob Griese came off the bench to replace Don Strock at quarterback and lead the Dolphins from a 17-3 deficit to a 20-17 win at Atlanta; and Cleveland came back from its Monday night loss to defeat the Chiefs 20-13, with Browns Kicker Don Cockroft joining eight other players with 1,000 or more career points.
