The strength of this tennis podcast is the subject matter expertise of the host and the big names he's able to bring on. I wish the audio quality was better for the out-of-studio phone interviews (the recent Kevin Anderson one sticks out in my mind as particularly difficult to understand), but I imagine that is the (forgiveable) tradeoff made in securing interviews with busy pro athletes, coaches, and commentators traveling the globe and squeezing in an interview from the practice court. I appreciate that Jon tends to take a cup-half-full perspective on the game and regards the historic performances of the Big 4 as something to celebrate, not complain about. I find the quality of this pod varies a lot and depends on the quality of the guest being interviewed. Jon and Jamie are always good, but sometimes the big names they interview are not as articulate or thoughtful as the slightly lower profile people they bring on. Favorite guests/episodes include: Nicole Gibbs, Michael Kosta, David Epstein, Martin Blackman, and Mike Bryan. Probably my favorite surprise moment was Michael Chang retelling the Sampras/Corretja match from the perspective of someone who stood to benefit in a big, historic way from Sampras losing. Least favorite moment was when Jon tried to equate Tiger Woods' comeback with Petra Kvitova's. Jon's typical sensitivity and sound judgment were way off that day: Back surgeries not withstanding, many of Tiger's problems were self-made; Petra was a crime victim. Her reaching the 2019 Australian Open final is the bigger and better story.
