Legendary Stanford Coach Frank Brennan shares some of the lessons he learned during the 21 years he coached the Cardinal (a tenure which saw 10 NCAA titles, twice as many as any other women's tennis coach). Brennan shared insights and anecdotes from a life in tennis spanning the time his father offered to restring the rackets of a young Billie Jean King, to his current volunteer coaching (under the watchful eye of his son, Assistant Coach Frankie Brennan).
