In a departure from preoccupation with big-name offensive players at skill positions, three defensive player and a center have been elected to the Pro Football Hall of Fame, it was announced yesterday.

Defensive tackle Bob Lilly of the Dallas Cowboys, defensive end David (Deacon) Jones of the Los Angeles Rams, center Jim Otto of the Oakland Raiders and cornerback Herb Adderley of the Green Bay Packers will be enshrined at ceremonies in Canton, Ohio, on Aug. 2, when the San Diego Chargers play the Packers in an exhibition game.

Lilly, all-America at Texas Christian, was the Cowboys' first-ever draft choice, in 1961.

The 6-foot-5 and 260-pound native of Throckmorton, Texas, played in 10 Pro Bowls, and the fifth and sixth Super Bowls. He had a streak of 196 regular-season games before missing the 1973 championship game against Minnesota because of a leg injury.

Adderley, 6-1, 200-pound native of Philadelphia, was Green Bay's No. 1 draft choice in 1961, from Michigan State. He joins Coach Vince Lombardi and four Packer teammates in the Hall of Fame.

Otto, 6-2 and 255-pound native of Wausau, Wis., was a center and linebacker at the University of Miami (Fla.), played for 15 seasons and was the only starting center the Raiders ever had over that period, in 210 straight games.

Jones, a 6-4 native of Eatonville, Fla., played at 272 pounds at South Carolina State and later at Mississippi Vocational before being drafted on the 14th round by the Rams.

He was a unanimous all-NFL selection for six straight years and played in seven straight Pro Bowls.
