NFL free agency is always an exciting time for fans as they eagerly wait to see who their teams will sign. However, overpaying a player with boom-or-bust potential can sometimes blow up in an organization's face, as we've seen plenty of times over the past decade.
One of the biggest free-agent busts of all time, falling just outside the last decade, came when Washington offered defensive lineman Albert Haynesworth a $100 million deal in February 2009. Missed offseason workouts, a failed conditioning test and subpar play eventually led to the two sides parting ways and an aggressive cap hit to Washington's books.
