  Title: 1993 Cleveland Browns season
  Passage: The 1993 Cleveland Browns season was the team's 44th season with the National Football League.  This season was notable for coach Bill Belichick deciding to bench, and then ultimately release, longtime starting quarterback Bernie Kosar in favor of Vinny Testaverde.  Kosar resurfaced during the season with the Dallas Cowboys, when he was part of the eventual Super Bowl champions as a fill-in for injured quarterback Troy Aikman.  The Browns get off to a 5-2 start despite the Quarterback Controversy.  Prior to the start of the season the Browns signed Free Agent Quarterback Vinny Testaverde.  Originally Testaverde was supposed to back-up his former University of Miami teammate Bernie Kosar.  However, when Testaverde performed better when given the opportunity to play some felt there should be a change at the Quarterback position.  However, the Browns went beyond that by unceremoniously releasing Kosar in the middle of the season.  The Browns lost their next four games and seven of their last nine games to finish with a 7-9 record.
