In 1817, Samuel Taylor Coleridge first described the notion of “suspension of disbelief.” Coleridge suggested that if it is possible to infuse “human interest with a semblance of truth” people will suspend judgment concerning the implausibility of the narrative.
This essentially describes most every sports fan during the off-season. BYU fans are as prone to this practice as any fanbase.
The human interest that BYU fans have collectively is found in the Cougars being amazing and the best they have ever been. The off-season fuels the suspension of disbelief fire with little semblances of truth or perceived truths in the form of rumors.
