I think for me 'The Catch' in 1982 by Dwight Clark beating my favorite team at the time. The Niners beat the Cowboys that day and I cried. Keith Smart 'The Shot' hitting the baseline shot giving Indiana the NCAA title in 1987 is up there and also Dale Earnhardt 'The Crash' getting killed in 2001 stands out. They all have something in common as my fan-ship for all has decreased in some way. When Dallas fired Tom Landry I despised Jones and the Cowboys, when Indiana fired Coach Knight I despised Miles and the Hoosiers. Since Earnhardt passed my liking for NASCAR has decreased as well.
1982 - Cowboys
1987 - Hoosiers
2001 - Dale Earnhardt Sr
