Ohio State basketball Coach Eldon Miller, under fire from fans for a string of recent losses, stepped down yesterday, effective at the end of this season, Athletic Director Rick Bay announced.

Bay said Miller agreed it would be in the best interests of the men's basketball program for the university to seek a new head coach at the end of this season. Miller's contract expires June 30, 1986, and will not be renewed, Bay said.

"I did not intend to reach a decision on this matter until the end of this season," Bay said. "However, Coach Miller came to me this morning and said he believed we should resolve the situation immediately. It was then we agreed to announce this would be his last season as the Ohio State men's basketball coach" . . .

Bear Bryant, winner of 326 games in almost 40 years as a head coach, was a unanimous choice for the National Football Foundation's College Football Hall of Fame.

Bryant died in 1983, 37 days after retiring as coach at Alabama, where he had a 232-46-9 record.

Starting his head coaching career at Maryland in 1945, Bryant also coached at Kentucky and Texas A&M before moving on to Alabama. His overall record was 326-106-7.

Bryant surpassed Amos Alonzo Stagg's record of 315 victories for a college football coach, but his mark since has been broken by Eddie Robinson of Grambling.

Bryant will be inducted into the Hall during an Alabama home game next fall and will be saluted at the foundation's annual awards dinner Dec. 9 in New York. . .

Only 39 percent of the football players and 18 percent of the men's basketball players at the University of Texas, a perennial football power, graduate while on scholarship, the Dallas Morning News reported. In contrast, Rice, constantly battling to stay out of the Southwest Conference football cellar, graduates 65 percent of its football players and 60.5 percent of its basketball players, the paper said.

Other SWC schools either refused to release graduation rates or do not keep such records. However, Southern Methodist Athletic Director Bob Hitch called the Mustangs' graduation rates "not good."

In 1979, Herbert Reynolds, executive vice president at Baylor and now its president, labeled "tragic" that school's abililty to graduate only one-third of its football players.

"A lot of them (athletes) are being used," said Mike Singletary, all-pro linebacker for the Chicago Bears and a Baylor alumnus. Singletary did not graduate while on scholarship at Baylor, but returned three years in the offseason to earn his business degree . . .

The Baylor men's basketball team will not be eligible for the 1986 SWC postseason tournament in Dallas because of NCAA probation, the SWC Executive Committee decided. Baylor also is ineligible for the national tournament . . .

Redshirt status has been officially given to 22 of West Virginia's 24 1985 freshman football recruits, including tight end Paolo Arnell of Washington, D.C., Coach Don Nehlen said. Kicker Charlie Baumann of Erie, Pa., a freshman, and outside linebacker John Kempf of Pittsburgh, a junior college transfer, were not redshirted.
