List Criteria: Upvote the worst sports collapses in history
Call them sports failures or call them upsets - either way, these sports teams and athletes embarrassed themselves and shocked people around the globe by making history, and not in a good way. These professional MLB, NBA, NFL, and NHL teams, as well as individual athletes all squandered leads, stunk up their seasons, or lost at the worst possible moments to create the biggest sports collapses of all time. These are the most notorious upsets in sports history.
At best, these teams and athletes prove that where there is great expectation is often where the biggest disappointments arise. At worst, they've made fools of themselves in such a way as for it to go down in history.
These sports teams had huge leads in games, were way ahead in the standings, or had nearly won a game, series, or championship, but at the last minute collapsed completely and lost after coming so close to victory. It's not the best way to remember these teams, but unfortunately their collapses live on in infamy.
