LOS ANGELES — Mina Kimes, a Yale grad turned investigative business reporter turned NFL analyst on ESPN, was winding her way along a hiking trail through a Pasadena forest on a recent afternoon, with her dog, Lenny, in tow. She wore a hoodie, leggings and a hat with a South Korean flag, a nod to her mother’s home country. As the path snaked back and forth across a stream, she picked up Lenny at every crossing, cradling him in her arms to keep his paws dry.
