Navin's tough negotiations and salary battles with Tiger players are legendary. In the 1920s, Tigers slugger Bob "Fats" Fothergill always had a weight problem, and Navin constantly rode Fothergill about it. When Fothergill came to Navin's office in the winter to negotiate his contract, he wore a big, heavy overcoat to conceal the weight he had put on in the offseason. Navin figured out what Fothergill was up to and turned the heat way up in his office. Navin then sat back and engaged Fothergill in a long, drawn-out conversation about his family, hunting, and anything but the contract. As sweat poured off Fothergill, Navin suggested that he take off the coat, but Fothergill insisted he was comfortable. When the conversation finally got around to the contract, Fothergill wanted to get out of Navin's hot office so badly that he accepted Navin's first offer.
