The 1955âÂÂ56 San Francisco Dons men's basketball team represented the University of San Francisco as a member of the California Basketball Association during the 1955âÂÂ56 NCAA men's basketball season. The Dons ended the season undefeated, becoming the first NCAA tournament champion to record a perfect season and the first team to go wire-to-wire as No. 1 in the AP and UP polls. San Francisco finished the season with a 29âÂÂ0 record (14âÂÂ0 CBA) and had won 55 consecutive games.
San Francisco won two straight NCAA titles behind a punishing defense led by Bill Russell, who turned shot blocking into an art form. He was also a much better scorer than history gives him credit for, averaging more than 20 points in both championship seasons. In 1956, Russell had support from guard K.C. Jones and a balanced lineup; besides Russell, five other players averaged between 7.1 and 9.8 points per game.
