"I haven't decided yet," said Favre, who was in Arizona for a Super Bowl-related activity. "We just played a little over a week ago. I'm going to take a few more weeks. Our coaching staff is coaching in the Pro Bowl next week. When they get done, [coach] Mike [McCarthy] and I . . . we'll just discuss it more in a couple weeks."
Favre, 38, had one of his best seasons in several years in 2007, leading the Packers to a 13-3 record and their first division championship since 2004.
He completed 356 of 535 passes for 4,155 yards, with 28 touchdown passes, 15 interceptions and a passer rating of 95.7. It was Favre's best passer rating since 1996 and the touchdown passes were his most since the 2004 season. In his second year under McCarthy, he managed games well and took better care of the football.
Green Bay lost to the New York Giants in the NFC championship game, keeping Favre from a third Super Bowl.
"The game the other day will not play into my decision making," said Favre, a three-time league most valuable player. "I'm not going to let one game affect my future one way or another. I think it's more whether I'm willing to go through the journey and the ups and downs. What if we start 4-0? Great. What if we start 0-4? Then how will I react? Do I want to put in the time in the off-season to prepare? That will decide it more than anything else."
Last season, Favre agonized over whether he would return to the Packers. It is generally believed that his wife and two daughters are in favor of him playing in 2008.
Favre will spend some time relaxing at his home in Hattiesburg, Miss., and discussing the decision with his family. But he made it clear he'd rather be preparing for the Super Bowl.
"I would much rather be preparing to play in this game," said Favre, who now owns most of the league's career passing records. "But that's the way it goes. . . . It would have been nice to be here but it's not the end of the world."
