PRO FOOTBALL—Jaded LA. sports fans, take note: The Rams are 4-0 and already two games up on the NFC West. Eric Dickerson ended his 46-day holdout in midseason form, ripping Seattle for 150 yards and three touchdowns in a Monday-night 35-24 thumping of the Seahawks. But Dickerson paid the toll on Sunday, missing much of the 17-6 win over Atlanta because of a tight left hamstring. Quarterback Dieter Brock took up the slack, completing 16 of 20 passes for 215 yards and two TDs. The other LA. team, the Raiders, compensated for its offensive woes by letting the defense score the points. Defensive end Lyle Alzado and defensive backs Lester Hayes and Sam Seale each scored TDs to lead the 2-2 Raiders to a 35-20 drubbing of New England. Kansas City, the AFC West leader, made its record 3-1 with a 28-7 thrashing of Seattle. Free safety Deron Cherry picked off four passes to tie a league record, and Bill Kenney threw two TD passes to Ste-phone Paige for the Chiefs. Denver fell a game back by losing to AFC East co-leader Miami 30-26. Dolphin QB Dan Marino ignored the 29° cold in Mile High Stadium to throw for 390 yards and three TDs. The surprising New York Jets matched Miami's 3-1 record by edging Indianapolis 25-20. Defensive heroics enabled the three teams atop the NFC East to remain tied at 3-1. Giant cornerback Elvis Patterson returned an interception 29 yards for a TD on the third play of overtime to lift New York past Philadelphia 16-10. At Houston, the Cowboys sacked Oiler QB Warren Moon a dozen times and swiped four passes in a 17-10 victory. Dallas kicker Rafael Septien kept the game close by missing four field goals. St. Louis strong safety Leonard Smith set up 10 first-half points with a blocked punt and an interception as the Cards jumped out to a 26-0 lead over Green Bay en route to a 43-28 win. Cleveland moved within half a game of AFC Central-leading Pittsburgh with a 21-7 upset of San Diego, which lost QB Dan Fouts for at least three weeks with an injured right knee. New Orleans shocked San Francisco 20-17, Detroit pummeled Tampa Bay 30-9, Minnesota outlasted hapless Buffalo 27-20, and NFC Central leader Chicago remained undefeated by embarrassing Washington 45-10 (page 26).

Pancho Carter passed Rutherford and crossed the finish line first, but the panel upheld Rutherford's protest because no green flag had been displayed.
