The Atlantic Coast Conference and C. D. Chesley Co. are being sued, and if they allowed rooting sections in federal court the multitudes who never get enough of ACC basketball televised live might roar: "Go, Raycom, go!"

You might also hear some shouts of "Enough, already!" But if Raycom Inc. of Charlotte, N.C., wins its antitrust case, it could open the door for other independent purveyors of the educated dribble, ACC style.

Raycom has gone to U.S. District Court, Charlotte, contending that with the member schools' surrender of TV marketing rights to the conference. "The ACC thus has created a cartel consisting of an exclusive pool of . . . more than 200 games" and sold some to Chesley "pursuant to an unprecedented, secret contract applicable to the 1980-81 and 1981-82 intercollegiate basketball seasons. During the 1980-81 season, Chesley telecast only about 33 of the more than 200 games" -- and blocked Raycom, which in 1979-80 found consumer and advertising demand sufficient for it to pick up nine games, from televising any more last season.

Last month, the suit notes, the ACC reaffirmed its arrangement with Chesley. The conference at the same time contracted with the NBC for some national broadcasts of games involving ACC teams.
