It's gonna be a closer game than people think, IMHO. Detroit always plays Minnesota tough.
That said, I'd expect about 200 yards and 2 TDs out of Favre, maybe 120 and a TD out of Peterson, and the Minnesota defense racking up several sacks and an INT or two. Visante Shiancoe would be the guy I think has a good week this week, versus Berrian, Rice and Harvin. Just a guess on my part...but I do know that if Favre put up Brees types of numbers in Week 2, Childress will be fired in the off-season, since he'll run Favre into the ground before November/December.
