Hall of Fame: Hockey (formerly)
He never actually stepped onto the ice, but he was enshrined in Toronto all the same. Alan Eagleson was a lawyer, promoter and hockey agent who became the first executive director of the NHL Players Union. On top of that, he argued for pro players to be able to participate in international hockey tournaments. But it was soon found out that his consolidation of power allowed him to profit immensely off of others.
He was convicted of fraud, embezzlement, and skimmed profits from player contracts, pensions, and tournaments. When he was exposed as a scumbag he resigned from the Hockey Hall of Fame as, in a unique twist of irony, 18 Hall of Famers banded together to request that either he be removed, or they'd all resign together.
