Back in February, Celtics guard Kyrie Irving created a bit of a stir when he appeared on then-teammate Richard Jefferson's podcast (when both were members of the Cavaliers) and expressed his firm belief that the Earth—the big round globe we all call home—is in fact flat. He had mostly held to his comments on the matter until September, when he went on a Boston radio show and told the hosts that, actually, his whole flat-earth thing was merely a bit designed to troll people, or start a conversation, or ... well, you try to make sense of this word salad.
