I welcome Joe Posnanski, senior writer at The Athletic, for a wide-ranging conversation starting with a discussion of Djokovic's and Osaka's wins at the Australian Open. He talks about what might be stopping the younger generation of men from dethroning Djokovic and Nadal, why Naomi Osaka is different, how much credit to give to coaches, and whether the outstanding crop of young American women is underreported. Joe also shares his thoughts about how to compare players across eras, whether we ought to pay more attention to the amateur era, and what he'd write about if he could write more about tennis.
