It's painful to see your team win nothing year after year, but almost 22 years into a century where technology is helping sports and there are still teams that don't even know how to get to the playoffs, it doesn't make sense.
The american sports teams do all kinds of tricks to improve their strategy, new quarterbacks, goalies, forwards, head coaches and executive heads but for some of them it doesn't work and those teams just never get out of the bad luck hole.
When a team hasn't won a championship for decades they usually become underdogs, but despite everything, the fans remain loyal to their teams regardless of the poor results season after season.
The NBA, NFL, MLB and NHL teams that have not won championships in the 21st century
Getting out of a championship losing streak is not as easy as it seems, while the losers try to get out of that hole, the other teams already know how to win for the upcoming season. The NFL and NBA are the two league with most teams without championships in the 21st century.
One of the saddest stories among the four big leagues is the Toronto Maple Leafs (NHL), they were highly dominant in the 20th century but they haven't won a Stanley Cup in over 55 years.
