re: What programs/franchises have a signature loss?

Kansas State - A&M in 1998. Automatica missed twice.

Golden State in 2016 - got Durant the next year, but still an epic choke

Memphis bball vs Kansas in 2008. Choke City at the line.

TCU vs Georgia 65-7

Gonzaga vs Baylor 2021 - broke them

New York Knicks 1994 vs Rockets Game 7 - Starks shoots like 5-28. Missed a potential game-and-series winning three in Game Six

Yankees choking away a 3-0 lead

Boston Bruins against the Panthers last year

Suns losing Game 5 vs the Bucks in the 2021 NBA Finals

Carolina Panthers - Superbowl

Bengals - choke against the Steelers in the Wildcard round in 2015. This game broke Antonio Brown

Virginia bball in the 2018 tournament. First #1 seed to lose to a #16, and lost by 20. They won the natty in 2019, but got refs like Bama

Yankees in Game 7 of the 2001 WS. 9-11 had just happened and the magic in Games 4 and 5 seemed to be a precursor to a coronation. Soriano hit a solo jack to put the Yankees up 2-1, and the GOAT closer came on, and gave up two runs in the ninth to lose.

Kentucky Football - Bluegrass miracle

UNLV - loss vs Duke in 1991 tournament- Tark the Shark
