Madden, now a game analyst for NBC-TV, made his comment Tuesday night on the "NFL Total Access" show on NFL Network during an interview with Rich Eisen and Rod Woodson.
"I don't know if it has to be in Green Bay," Madden said, referring to Favre returning to play in the National Football League for his 16th season. "It just sounds like to me that if he's going to play - and again I have not talked to him, I've just listened to him - it sounds like he may be setting himself up to be traded. He would probably want to play, but he wants to play with a team that has a chance to win. The Packers really don't look like they are going in that direction right now, so maybe he's talking about another team."
Madden said that Favre repeatedly has said to him and others that he does not want to end his career with any team but the Packers.
"But I wouldn't be surprised if there was a trade," Madden said. "There are a number of teams that could use him. . . . There are a lot of moving parts in this that could include the draft and could maybe include Brett Favre."
