Coach Tom Landry of the Cowboys lost another aide yesterday when his quarterback coach, John Mackovic, signed a five-year contract to coach the Kansas City Chiefs.

Mackovic replaces Marv Levy, who was fired for a 3-6 season.

Mackovic was in Dallas two years. Before that, he coached Wake Forest three years. He's Landry's third offensive aide to get an NFL head coaching job in three years. Dan Reeves went to Denver in 1981 and Mike Ditka to Chicago in 1982 . . .

In Tampa, Coach John McKay of the Buccaneers lost his quarterback coach, too, but willingly. He fired Bill Nelsen and offensive line coach Bill Johnson.

Golf: At Monterey, Calif., Joe Inman shot a seven-under-par 65 and took the first-round lead in the Bing Crosby Pro-Am when Tom Watson lost his ball 60 feet up in the air.

"I was seven under (and tied for the lead) going to 18, then I knocked it into the top of a tree and it never came down," he said. "That's the first time that's ever happened to me."

It cost him a double bogey. He finished at 67 and tied with Gil Morgan. Fred Couples and Ken Green shot 66 . . .

In Miami, rookie Lauri Peterson shot a 69 at Turnberry Isle Country Club and leads the LPGA event. Tied at two-under-par 70 in the $150,000 tournament were Debbie Massey, Janet Coles and Anne-Marie Palli. At 71: Marty Dickerson, Lauren Howe, Vicki Fergon, JoAnn Washam, Nancy Lopez, Alice Ritzman and Jeannette Kerr.

Defending champion JoAnne Carner and Pat Bradley had 72s.

"My goal this year is basically to find the fairway," Peterson said. "I only hit seven or eight fairways out of 14."

"You really don't expect a rookie to lead," Carner said.
