It's not a scenario Vikings coach Brad Childress is spending much time pondering.
"You can make an argument for one side and an argument for another," Childress told The Associated Press on Tuesday. "But I can't waste a lot of energy. All I can do is take a look at the waivers every day and see if there's somebody that's better than somebody on the roster. That's really all you can evaluate."
So, Childress and the Vikings are moving on with Tarvaris Jackson, who went 8-4 in 12 starts last season, despite his eight touchdowns and 12 interceptions. Childress is counting on the third-year pro to take a step forward this season.
"He's got the experience of being the guy every Sunday," Childress said. "It's not, ‘Stand there and watch.' It's on you. You learn that you just have to keep shooting. You have to keep throwing. You can't get tentative. I like some of those experiences he went through."
Manning, Favre and the streak
Assuming Favre stays retired, or comes out of retirement only to sit on the bench in Week 1, the No. 1 challenger to his record-starts streak is Indianapolis quarterback Peyton Manning.
Manning, however, underwent surgery Monday to remove an infected bursa sac in his left knee. The Colts say he'll be out four to six weeks. On the long end of the timetable, that would have him healthy by the last week of August, plenty of time before they open the regular season Sept. 7 against Chicago.
Favre retired with 253 consecutive regular-season starts. Manning has started all 160 games of his 10-year career. Tom Brady is a distant third among active players (if you want to call Favre active) with 110 starts.
Interviewed by The Indianapolis Star, Colts President Bill Polian said "no one's losing any sleep over this."
"Don't forget, he's had every practice for 11 years," he said. "I don't know that missing some practice time is going to do any harm at all, to be truthful with you."
Bears land Jones
The Chicago Bears signed former Detroit Lions running back Kevin Jones to a one-year contract on Tuesday. Jones rushed 3,067 yards and 24 touchdowns in four seasons but was released by Detroit because of a history of injury problems.
The Packers were one of several teams who attended Jones' workout last month. They have questionable depth in the backfield behind unsigned Ryan Grant.
Linebacker Carl-Johan Bjork was signed by the Bengals as an international practice squad player, a source with access to the NFL transactions wire told Packer Report. He played three seasons for Amsterdam before NFL Europe folded. He spent last season on the Packers' international practice squad.
