The Bucks joined the NBA in 1968 and won just 28 games. Everything changed in 1969 when they won a coin toss to draft UCLA's Lew Alcindor (later Kareem Abdul-Jabbar). Alcindor won the Rookie of the Year in 1969 and led the team to 56 wins. The next summer, the Bucks acquired Oscar Robertson. This dynamic pair led the Bucks to 66 wins in 1971 and their lone NBA championship, the quickest ever for an expansion franchise. The Bucks continued to play well with this pair, but their success slowed after Robertson retired and Alcindor forced a trade to Los Angeles before the 1974-75 season.
