After competing during the
1962 preseason, Dooley officially retired, but he was soon added as an assistant coach. Three years as the team's
wide receivers coach were followed in
1966 by his elevation to the role of the team's
defensive coordinator. The move followed the departure of
George Allen to
Los Angeles, with Dooley quickly becoming known for his innovative strategies. These included flip-flopping the team's defensive tackles during that first year, then using five men in the defensive backfield on third down in
1967, which became known as "the Dooley Shift" and now is referred to as the
nickel defense. In February
1968, Dooley was returned to the offensive side of the ball, but that status changed just months later when 73-year-old
George Halas announced his retirement as head coach on May 27 due to
arthritis. Dooley, 38, was promoted and introduced as head coach the following day. The Bears won half of their games that season, but the team collapsed the
following year with a franchise-worst record. The lone win that year came at midseason against the league's other team, the
Pittsburgh Steelers. In November, running back
Brian Piccolo was diagnosed with cancer, and died the following In
1970, the Bears improved by five games to finish with a record, and appeared to be on track for major improvement the
following year by winning five of their first seven games, including a victory in week seven over the eventual
Super Bowl champion
Dallas Cowboys. However, the second half of the campaign proved to be a disaster, with just one win in the final seven contests, including a humiliation on
Monday Night Football on November 29 to the other Super Bowl participant, the
Miami Dolphins. It was the second of five consecutive losses to conclude the season. The inevitable result of the 1971 collapse came a month later when Dooley was fired on December 29, the first Bears coach ever to suffer that fate. Dooley soon signed as the linebacker coach for the
Buffalo Bills, but resigned after just one season. After sitting out the season, Dooley was named an assistant with the fledgling
World Football League's
Southern California Sun. The job came just one week after he had filed for
bankruptcy, citing nearly half a million dollars in debts, including
$320,000 to former Bear player and assistant
Sid Luckman. In a parallel of his personal problems, Dooley's job ended with the financial problems of the league, at which point he went to work for Luckman at Cellucraft, as a national account sales manager for flexible packaging products, for the next five years. On October 12,
1981, he was rehired by the Bears as an offensive consultant, a decision that caused conflict with the team's coaching staff, causing them to consider him something of a spy for management. After the conclusion of the season, Dooley and all the other coaches were dismissed, but the team's new head coach
Mike Ditka, who had played under Dooley two decades earlier, hired him to scout game film of upcoming opponents. Dooley flourished in his new job, aiding the Bears's rise and playing a part in their dominating
1985 season that was capped with a 46–10 victory over the
New England Patriots in
Super Bowl XX. In 1997, he was honored by his alma mater with a spot in the Miami Hurricanes'
Ring of Honor. ==Death==
