In the 1967 NBA Finals, the Sixers were pitted against Chamberlain's old team, the San Francisco Warriors of his one-time backup Nate Thurmond and star forward Rick Barry. The Sixers won the first two games, with Chamberlain and Greer taking credit for respectively defensive dominance and clutch shooting, but San Francisco won two of the next three games, so Philadelphia was up 3–2 prior to Game 6. In Game 6, the Warriors were trailing 123–122 with 15 seconds left. For the last play, Thurmond and Barry were assigned to do a pick and roll against Chamberlain and whoever would guard Barry. However, the Sixers foiled it: when Barry ran past Thurmond's pick and drove to the basket, he was picked up by Chet Walker, making it impossible to shoot; Thurmond was covered by Chamberlain, which made it impossible to pass. Barry botched his shot attempt, and the Sixers won the championship. He said: "It is wonderful to be a part of the greatest team in basketball ... being a champion is like having a big round glow inside of you." He contributed with 17.7 ppg and 28.7 rpg against fellow future Hall-of-Fame pivot Nate Thurmond, never failing to snare at least 23 rebounds in the six games. Chamberlain himself described the team as the best in NBA history. In 2002, writer Wayne Lynch wrote a book about this remarkable Sixers season, "Season of the 76ers", centering on Chamberlain.
