Look, I know ESPN is not explicitly saying anyone should regard Tebow as the best southpaw in sports history, but it put his picture in here, alongside Steve Young, Phil Mickelson, Babe Ruth, Sandy Koufax, and Bill Russell, and asked readers "Who's the best lefty in sports history?" so the WWL (or some poorly paid "social media intern" in Bristol) obviously thinks he should be in the conversation. I can only assume photos of Pelé, Ken Griffey Jr., Martina Navratilova, Mark Spitz, and Wayne Gretzky were not available for use, to name a few out of potentially hundreds of other candidates.
Thanks Kyle B. for the tip.
