DALLAS — Mike McCarthy will not return as coach of the Dallas Cowboys, who are going on three decades since their last Super Bowl title, owner Jerry Jones said Monday. Jones said the organization and McCarthy mutually agreed to part ways. A search for the team’s next coach begins immediately, he said. “I have great respect for Mike, and he has led the team through some very unique and challenging times during his tenure,” Jones said in a statement. McCarthy’s contract expired on Jan.
