As an owner, Shore could be cantankerous and was often accused of treating players with little respect. He commonly had Springfield players who had been out of the lineup perform maintenance in the Eastern States Coliseum, the Indians' home, referring to them as "Black Aces". Today, the term is commonly used to refer to extra players on the roster who train with the team in case of injury. Despite this, the Indians prospered under his ownership, making the playoffs 12 times and winning three Calder Cups in a row from 1960 to 1962. During the 1967 season, the entire Indians team refused to play after Shore suspended three players without pay, including future NHL star Bill White, for what he said was "indifferent play". When the team asked for an explanation, Shore suspended the two players who spoke for the team, one of whom was Brian Kilrea. Alan Eagleson, then a little-known lawyer and sometime politician, was brought in to negotiate with Shore on the players' behalf. The battle escalated for months, ending with Shore giving up day-to-day operation of the club to the Los Angeles Kings; the genesis of the National Hockey League Players' Association stems from that incident. Shore took back full control of the team in 1974, changed its name back to the Indians and restored its traditional blue-white-red scheme. He continued to own the team until he sold it in 1976.
