 On March 4 , 2008 , Favre formally announced his retirement . Although Favre stated that he had been willing to play another year , he felt that another season would only be successful if he led his team to another Super Bowl victory . He added the chances for a Super Bowl win were small , and that he was not up for the challenge . At his press conference , Favre openly wept about leaving the NFL . He stated that his decision , regardless of what was being said in the media , had nothing to do with what the Packers did or didn 't do . Seeming to contradict statements made by his agent , Bus Cook , Favre said that his decision to retire was based on the fact that he did not want to play anymore . He said during the conference , " I know I can play , but I don 't think I want to . And that 's really what it comes down to . "
