Just ask Chad Pennington who was the odd man out for the Jets in Brett Favre's previous change of heart on retirement. He only went to the Jets's rival Miami and was comeback player of the year, leading them to their first division title since 2000 which included a victory the last weekend of the season against the very same man who replaced him.
Now Jackson must be the one on his way out since Sage Rosenfels was traded for in the offseason. Plus, we haven't really seen what Rosenfels can do. He's had some moments as a backup but never fully as the guy. Jackson on the other hand has had many an opportunity.
I doubt if and when Jackson is released the same scenario will happen with Chad Pennington. FIrst of all, the rest of that division is pretty much set at the quarterback position, and at this point his best possible choice is competing for a backup role. But if something happens to the one he's backing up, look who's back in.
So many players especially quarterbacks have been released then showed what they could do in other cities. Again, look at Chad Pennington for exhibit A. Jim Plunkett was run out of New England and then San Francisco before winning two Super Bowls with the Raiders. And pretty much any quarterback ever exiled from Tampa Bay (Doug Williams, Steve Young, and even Trent Dilfer) lands on their feet.
Even if Favre didn't play or even if he gets injured, he'll still most likely have to wait in line behind Sage Rosenfels. And if he does get in the game, you can expect not only the crowd, but perhaps some of the team to lose confidence.
Someone who may be more affected won't even suit up for the Vikings. Head coach Brad Childress knows his job is on the line. But having Brett Favre might not be the boost he needs. Just ask Eric Mangini, Favre's ex-coach with the Jets who was fired after the team had a meltdown.
Mangini was able to find another head coaching position in Cleveland, a place where losing is common place so there won't be as much of a rush to win. But depending on job availability, Childress might have to wait out a season or two for a head coaching job or go back to being an assistant again.
If he does lose his job and Brett Favre unretires again next year with another team, Childress could always be Favre's chauffer, a role he didn't have a problem with on Tuesday.
