A sports dynasty is a team that dominates their sport or league for multiple seasons or years (see The Killer Bees). Such dominance is often only realized in retrospect. Some leagues maintain official lists of dynasties, often as part of a hall of fame (e.g., National Hockey League), but in many cases, whether a team has achieved a dynasty is often subjective, and can be a frequent topic of debate among sports fans. The most widely accepted sports dynasties are those with multiple championships over a limited period of time, either consecutively with or without interruption (e.g., UCLA Bruins men's basketball from 1964 to 1975), and The Alabama Crimson Tide (NCAA football) 2009–present); or non-consecutively (e.g., the Oakland/Los Angeles Raiders of the late 1970s and early 1980s or the Liverpool and Juventus association football teams of the 1980s). In a few cases, a dominant team without championships might be recognized as a dynasty (e.g., the Buffalo Bills of the early 1990s, the MLB Atlanta Braves (also of the 1990s), the NBA Detroit Pistons from 2003 to 2008 (who won an NBA Championship in 2004, reached the NBA Finals in 2005 and advanced to the NBA Conference Finals in each of the next three seasons), or the Minnesota Vikings of the 1970s), though this is likely to be disputed.
