Jeff is joined by Carl Bialik and Jeff McFarland, trying out a new format for a new year. We dig into the new ATP Cup, considering whether the format is appealing to players and fans, how we should feel about odd matchups between players hundreds of ranking places apart, and--most importantly--what captains should be doing with the stats available to them. We also look at the top of the WTA ranking table, considering whether Ashleigh Barty will continue her reign for another twelve months, or if Bianca Andreescu--or Karolina Pliskova--will topple her.
