Discrimination in sports' upper echelons remains very much an issue for civil rights activists, take it from the Southern Christian Leadership Conference.

Joseph Lowery, SCLC president, put Commissioners Pete Rozelle and Bowie Kuhn on notice yesterday that SCLC wants to meet with them -- with the Congressional Black Caucus and the National Conference of Black Lawyers joining in investigation of professional football and baseball.

Lowery, in an Atlanta press conference, zeroed in on the NFL fact that "there are not any, nor have there ever been, black (head) coaches and no black offensive or defensive coordinators"; and on baseball's ruling that Willie Mays had to give up his New York Mets job in order to accept employment by a casino. That Kuhn decision, says Lowery, "seems to be inconsistent with . . . involvement of other baseball personnel, including owners, with companies that own or operate gambling enterprises" . . .

William and Mary's search for a football coach, according to a Williamsburg report, has narrowed to six prospects, all former W&M players: two NFL assistants, three college sssistants -- and the coach of the perennially potent Annandale High teams, Bob Hardage . . .

In Huntington, W. Va., the continuing saga of Coach Sonny Randle finds 11 of his Marshall U. Players have quit since the end of his inaugural (1-10) season. But Randle says most of the departees just weren't good enough, and never fear, watch his current recruiting -- especially now that he and staff are yielding to upstairs pressure to clean up the act. The former Virginia coach admits his language was "getting out of hand; they wanted that to be toned down and for us to control it as much as possible and I think great strides were made in that direction" . . .

You were wondering maybe, whether 2-14 Detroit or 2-14 San Franciso "won" first pick in the 1980 NFL draft? It's Detroit. Billy Sims? . . .

Terry Bradshaw and Willie Stargell, physical and inspirational leaders of championship Pittsburgh teams, are Sports Illustrated's sportsmen of the year. The Steeler-Pirate tandem marks only the second time in 26 years (with John Wooden-billie Jean King, 1972) the magazine has split the honor . . .

Jim Steele, disillusioned Diplomate defender who bucked at season's end to go with buddy Paul Cannell out the trade door, suddenly is damaged goods. The three-year Dip, a frequent spark plug for Coach Gordon Bradley, suffered knee damaged playing Major Indoor Soccer League weekend before last, for Pittsburgh on loan from the the strictly outdoor Dips. Dr. Carl MacCartee removed the anterior cruciate ligament from Steele's left knee yesterday at GWU Hospital; prognosis good. Six weeks in a cast and he might be able to begin workouts two weeks the thereafter . . .
