Center Darryl Dawkins, looking better to the Philadelphia 76ers hurt than he did healthy, has a five-year renewal worth $3.5 million, plus incentive clauses . . . Catcher Gary Carter will go to Montreal Expo training with baseball's fattest contract outside New York, to be signed Monday for maybe $15 million (U.S.) for eight years.

In Philly, Sixers owner Harold Katz credits Dawkins' change of agents with turning trade thoughts to visions of the giant striving anew to achieve the greatness hoped for when he joined the NBA team out of high school in 1975.

The coaches of powerful teams must be able to maintain perspective . . . retain the winning integrity of their players and the unity of their team without humiliating and degrading their opponents."

Norte Vista opted not to be Poly's 75th straight victim in a rematch due last night. Norte Vista (0-17) lost, 84-7, Tuesday to Riverside North, then forfeited to Poly. But look, Coach T.J. Beinias said, it is his superiors' decision: "The girls want to play. They don't want to be called quitters."
