Soon after his retirement, he became coach and general manager of the second-year Detroit Cougars at the suggestion of NHL president
Frank Calder. At first, the team struggled under his leadership, making the playoffs only two times in his first five years at the helm. A name change to the Detroit Falcons in 1930 did not improve the team's performance. Detroit's fortunes changed in 1932, when
Chicago grain merchant James E. Norris bought the Falcons and renamed them the Detroit Red Wings. Norris gave the Red Wings the financing they needed to become an NHL power. Adams led the team to three Stanley Cups before stepping down in 1947 to concentrate on his duties as general manager. His coaching career tallied 413 wins, 390 losses, and 161 ties, including a 52–52–1 coaching record in the playoffs. Most of those wins came without a contract; when Norris bought the team he'd torn up Adams' contract and given him a year on his job on probation and a handshake. As it turned out, one year became 15 years. He was the winningest coach in Red Wings history until
Mike Babcock passed him late in the 2013–14 season. By 1947, Adams had built a farm system that produced
Alex Delvecchio,
Terry Sawchuk,
Ted Lindsay,
Red Kelly,
Sid Abel, and most notably
Gordie Howe. It was this core group of players that led the Red Wings to seven straight regular-season first-place finishes from 1948 to 1955, along with four more Cups—making Adams the only man to have his name on the Stanley Cup as a player, coach, and general manager. Adams was known for being wary of letting his teams get complacent, and was not shy about orchestrating blockbuster trades to keep them on their toes—a philosophy which won him the nickname "Trader Jack." His impulse was slightly restrained after Norris died in 1952 and was succeeded by his daughter,
Marguerite Norris. She and Adams never got along very well. While she could have summarily fired Adams since he was still without a contract, she did not do so. However, Marguerite was forced to turn over control of the team to her younger brother,
Bruce Norris, in 1955 after losing an intrafamily struggle. Bruce voiced full confidence in Adams, and the trading resumed anew. During their seven-season run in first place, many thought the Red Wings would rule the league for years to come. However, just days after Bruce took over the presidency, Adams traded away eight players from the 1955 champions. Years later, Howe wrote that Adams' reasoning for the trades still "def(ied) explanation," and argued that the trades opened the door for the
Montreal Canadiens to win five Cups in a row (and nine in 14 years). Although the Red Wings remained competitive until the late 1960s, Howe believed the trades "sapped us of the firepower we needed to win another championship." In
1957, Adams traded
Ted Lindsay to Chicago because of union-organizing efforts and had other players affiliated with the effort sent to the minors. As part of the
union busting efforts, Adams spread fake rumours attributing Lindsay as criticizing his former teammates. Adams also showed a fake contract to Detroit reporters, claiming Lindsay was being paid $25,000 per year, when he was being paid $12,000. The efforts resulted in most of the core of this team leaving town and eventually led to Adams being fired in 1963. His 36-year tenure as general manager is the longest in NHL history. He served 31 of those years while still on probation; after 1932 he never signed a contract with the Wings. His ouster from the Red Wings also ended 46 consecutive years at the major league level in hockey. Adams had also been involved in an incident in 1942, when he had an outburst due to his belief of biased penalty calling, which led to a fit of rage and ultimately a referee getting punched in game three of the
1942 Stanley Cup Final, thus becoming the first coach to be suspended in a Final. In 1963, Adams became founding president of the
Central Hockey League, a post he held until his death at his desk in 1968. ==Career statistics==
