During an interview on Tuesday with Olympic gymnasts Simone Biles and Aly Raisman, Bob Costas said that Biles "wasn't that well known before the Olympics." Sure, she's the only woman to ever win back-to-back World Championships, and she'd already won the P&G all-around title four years in a row (something that's only ever happened two other times). But she's probably not really well known to people who don't follow sports, or have a television, or live above ground (no offense meant to mole people. All love.)
