On the 165th episode of the GreatBase Tennis podcast two senior citizens, Steve Smith and Mark Costello, have a conversation. They have known each other since 1964, so theoretically, they should have some wisdom.When asked, the old tennis coach and the old hockey coach agreed that their chat might be best to hit the editing floor. However, the producer of the GreatBase Tennis podcast (Ivan Ozerets) insisted that worthwhile and meaningful points were made.
