Coach Tom Landry says he will consider trading anyone on the Dallas Cowboys -- including previous untouchables Randy White and Tony Dorsett -- if it results in acquisition of an explosive offensive player.

"This year for the first time we don't have the luxury of saying that these guys are untouchables," Landry told the Fort Worth Star-Telegram. Perhaps indicating he feels Dorsett has seen his best days, Landry said gaining an impact running back is his priority. Next would be a great wide receiver.

"Other than quarterback, a talented running back can change things quicker than any other position," Landry said. "And you don't get them unless you take them in the first five picks of the draft."

It was via trade with Seattle that Dallas positioned itself to draft Dorsett in 1977 . . .

In Scranton, Pa., almost 200 people paid their last respects to Jim Crowley, last of the 1924 Four Horsemen backfield of Notre Dame and coach of Fordham's 1930s teams featuring the Seven Blocks of Granite line. Crowley, 83, died Wednesday.
