While it is feasible in most major sports, it is extremely unlikely in some, such as basketball. Shutouts are commonly attributed to strong defensive performance, even when a poor opponent offense may be equally to blame. There have been several instances where a game ended in a complete blowout by both teams, but the opponents failed to score any points. The first known instance of a basketball game ending in a shutout occurred on March 4, 1954, when the New York Knicks defeated the Philadelphia Warriors, 97-0. This record still stands today. Another example came on February 15, 2007, when the Boston Celtics beat the Detroit Pistons 100-0. That night, Kevin Garnett scored 50 points and Paul Pierce added another 30 for their respective teams. It was also noted that Ray Allen made all 10 of his free throw attempts. In addition, there was one episode in the NBA during the 1971-72 season when the Los Angeles Lakers played against themselves (i.e., they took on their own team during practice). The final score was 120-118 in favor of the Lakers. Such games are often referred to as "zones". Finally, there was one game in 1902 where Alva Brooks' team was actually shut out by its own players.
