He returned to manage the American team in Cortina d'Ampezzo at the 1956 Winter Olympics, which resulted in another silver medal and a second-place behind the Soviet Union.

[2][10] He received the Lester Patrick Trophy during the 1993–94 NHL season, in recognition of his contribution to ice hockey in the United States.
