Chicago Bears Coach Mike Ditka would be interested in succeeding Cowboys Coach Tom Landry, the Dallas Morning News reported yesterday. Landry, 62, has not announced his plans to retire and will coach in 1986, but there is speculation that he will step down soon.

"I would be interested in going back to Dallas if the opportunity came about," Ditka, a Cowboys tight end from 1969 to 1972 and assistant coach from 1973 to 1981, told the Morning News.

Cowboys President Tex Schramm said Ditka and Denver Broncos Coach Dan Reeves, also a former Cowboys player and Landry assistant, "would both get very early consideration since we know them and know their capabilities." . . .

The Bears have withdrawn their latest contract offer to star defensive end Richard Dent, said General Manager Jerry Vainisi.

Vainisi said Dent's agent, Everett Glenn, did not respond to a 5 p.m. Wednesday deadline imposed by the team for their three-year, $1.8 million offer. Dent, 25, who was voted most valuable player in Chicago's Super Bowl victory over New England, is seeking a three-year contract worth $2.28 million.

"If they want it, fine," Vainisi said. "If they don't want it, the heck with them."
