The term for a collapse in competitive outcome is referred to as a upset. An upset occurs when a lower-ranked, less-favored competitor or team defeats a higher-ranked opponent. Upsets can take place in various sports and often lead to significant shifts in tournament dynamics and expectations. These unexpected results can boost the morale of underdogs while potentially demoralizing favored teams. Upsets highlight the unpredictable nature of sports, reminding fans and competitors alike that anything can happen in competitive play.
