In an exclusive interview with the Associated Press, Favre said the fate of Sherman would play a role in his decision on whether to play again next year.
"I don't think there's one specific thing that would make me say yeah or no," Favre said. "It's just a culmination of a lot of different things, that being one of them. Maybe you're on the verge of saying yeah, and then you say, 'You know what, do I really want to sit in meetings and have to learn something all over again?' That could be the straw that breaks the camel's back."
Since being traded to Green Bay in 1992, Favre has played in the West Coast offense. While the offense only vaguely resembles what he directed during his early days with Mike Holmgren, Favre has taken part in the system's evolution. The idea of learning a completely different system sounds like a challenge Favre is unwilling to tackle.
"It would be so hard for me to learn something new in a year," Favre said. "It would just be so difficult. I mean, it could be done. Anything can be done. We're talking about just the logistics of the Xs and Os and stuff. But when you've spent 14 years, all they have to do is come in and say right now ... instead of odd being to the left, now it's going to be to the right. You see where I'm coming from?
"It's no different than my first time in Tokyo, you're driving on the wrong side of the road and it was hell. And I didn't drive; I just rode."
Favre's decision isn't entirely hitched to Sherman's, however. At this point in his career, Favre is playing for victories. At 1-6, the grind of endless hours of film study and practice are wearing on Favre more than ever before.
"You spend all this time — people think I just show up on Sundays and we play," Favre said. "I'm here taking a damn nap here at lunch, spend all day and watch film at night. For three hours. And if it doesn't go your way, it's so disappointing all the time you've put into it."
At the same time, however, Favre doesn't see the team's near future as hopeless.
"I think it comes down to a couple draft picks and luck, obviously, good luck, and very easily we could be sitting here and be totally different (near year," Favre said. "I'm well aware of that. I mean, I don't sit here and say, 'It's going to take a while.' You get a good crop of players, you get a couple veterans that you might bring in, it's amazing how it can transform your team.
"And then, in this division, not only is it open this year, it's open most years. I know that if I come back next year, we could be right back in the thick of it."
Favre has had a season of wild ups and downs. Entering last week's game at Cincinnati, Favre was leading the league in touchdowns. He added one to that total, giving him 15, but he was intercepted a career-high five times. However, he is completing a career-best 66.7 percent of his passes despite missing, among others, Pro Bowl wide receiver Javon Walker and his top two running backs.
