The Vikings flirted with QB Brett Favre for two years, and the grizzled veteran showed why the team wanted him so bad in Sunday’s win over the 49ers. Judd Zulgad of the Star Tribune looks at Favre’s impact on the Vikings:

Brett Favre looked tired and felt even worse late Sunday afternoon as he stood at a lectern inside the Metrodome. “I’m worn out,” he said. “Believe me, I could fall [over] right now.”

At that point, Favre knew what many in the announced crowd of 63,398 probably felt about a half-hour earlier when he completed a 32-yard last-gasp touchdown pass to wide receiver Greg Lewis on third-and-3 with two seconds remaining, giving the Vikings a 27-24 victory over the San Francisco 49ers.

Some more notes from around the Web:

• After losing to the Packers on Sunday, St. Louis could be the new Detroit. St. Louis now holds the longest losing streak (13) in the league. How will the team react in coming weeks?

• Lions rookie QB Matthew Stafford helped lead the Lions to the win over the Redskins and snapped the team’s losing skid, giving the kid some much needed confidence in the processes.

• Fail to the Redskins: The team is reeling after losing to the Lions. What is next?

• Jets QB Mark Sanchez is not playing like a rookie, and he has the complete faith of his teammates.

• Eagles QB Kevin Kolb is proving his chops at quarterback.

• The Falcons suffered a thumping loss but learned a needed lesson for a young team still searching for its identity.

• Patriots QB Tom Brady is getting up to speed. The team has not looked sharp, but the Patriots are 2-1.

• The Bengals finally knocked off the Steelers, and for fans in Cincinnati, it was a long time coming.

• Raiders Nation — one of the most loyal backings of any sport – is starting to lose patience with the team and QB JaMarcus Russell.
