The Browns have won no titles since Jim Brown retired.
If only the current edition of the Cleveland Browns was considered, the Browns might be higher on this list.
However, the Browns were once a proud franchise that won four NFL Championships between 1950 and 1964.
They had arguably the greatest player in NFL history—Jim Brown.
Brown retired in 1965, and the Browns have not won a Championship since. They are one of only four teams that has not played in a Super Bowl.
In the 1980's they were the victims of "The Drive" and "The Fumble."
In 1996, owner Art Modell moved the team to Baltimore and changed their name to "Ravens."
In a unique deal, the City of Cleveland retained the name "Browns." They re-entered the NFL, essentially as an expansion team, in 1999.
Since then they have a dismal regular season record of 68-140. Their only playoff appearance was in 2002, when they lost to the hated Pittsburgh Steelers.
Adding insult to injury, the team the old Browns became—the Ravens—won Super Bowl XXXV.
