Previewing Minnesota's preseason finale

Posted by ESPN.com’s Kevin Seifert

The NFC North preseason will draw to a close Friday night at the Metrodome, where Minnesota’s backups will host Dallas’ second- and third-teamers. It should be a blast.

Starters will play … sparingly, if at all. And, once again, quarterback Brett Favre will sit this one out.

I’ll be watching … for clues to tell us which quarterback will get the heave-ho. Assuming the Vikings don’t plan to keep four quarterbacks, Favre’s arrival means that Sage Rosenfels, Tarvaris Jackson or John David Booty will have to go. I’d be shocked if it’s Rosenfels, who signed a contract extension in February. Conventional wisdom suggests it will be Jackson, but I’m not convinced. To this point, there is no indication of interest on the trade market and I wonder if coach Brad Childress would be willing to part with his long-time project. Booty is eligible for the practice squad. Would anyone claim him on waivers? That’s a risk, but one that might be worth taking. Favre-Rosenfels-Jackson is a stronger group than Favre-Rosenfels-Booty.
