Here is a comprehensive summary of the Cleveland Browns:

The Cleveland Browns are a professional American football team based in Cleveland, Ohio, competing in the AFC North division of the NFL. Founded in 1944 by Paul Brown and Arthur B. McBride, they dominated the All-America Football Conference (AAFC) with four championships before joining the NFL in 1950, where they won titles in 1950, 1954, 1955, and 1964—playing in their league championship game an unprecedented ten consecutive years. In 1995, owner Art Modell moved the franchise to Baltimore (becoming the Ravens), but the NFL kept Cleveland's name, history, and intellectual property in trust, allowing the Browns to resume play in 1999 via an expansion draft. Since their return, the team has struggled mightily, enduring a 0–16 season in 2017, a 17-season playoff drought, and just one playoff win (2020), while also cycling through 42 different starting quarterbacks. Known for their brown, orange, and white colors and a helmet without a logo, they remain one of only four NFL teams to never appear in a Super Bowl, and their long-time rivalry with the Pittsburgh Steelers has recently tilted heavily in Pittsburgh's favor.
