Forget the fickleness, the wavering and the constant stroking of his ego – Brett Favre was worth it for the Minnesota Vikings.

The Vikings remained undefeated in 2009 following their thrilling 33-31 victory over the Baltimore Ravens on Sunday. For all intents and purposes, the Vikings should have won by double-digit points but they blew leads as large as 14-0 in the first quarter and 27-10 in the fourth.

It was Favre that once again stepped up when Minnesota needed it most. After Baltimore shocked the Metrodome crowd by taking its first lead of the game at 31-30 with just over three minutes remaining, Favre found Sidney Rice on a 58-yard reception that got Minnesota down to Baltimore’s 18-yard line. Head coach Brad Childress then decided to play for the field goal by calling three consecutive running plays and setting up a Ryan Longwell 31-yard field goal to give the Vikings the lead back at 33-31. Favre and Minneosta then had to hold their collective breaths as Ravens kicker Steven Hauschka missed a potential game-winning 44-yard field goal as time expired.

Putting aside Minnesota’s near-collapse for a second, Favre and Adrian Peterson were incredible. Favre completed 21 of 29 passes for 278 yards and three touchdowns, while Peterson rushed for 143 yards on 22 carries. I don’t know if Peterson is opening things up for Favre, Favre is opening things up for Peterson or if it’s just a perfect mix of both, but it’s working for the Vikings.

But while I hate to pop the Favre-magic balloon, this was the second time this year that the Vikings got lucky inside the Metrodome. The first time was against the 49ers when Favre found Greg Lewis in the back of the end zone on an improbable touchdown pass. Had San Fran been in a normal defense, Minnesota would have suffered its first loss of the season. And had Hauschka made the field goal today, the Vikings would have lost again. It certainly wasn’t a chip-shot, but that’s a field goal Hauschka has to make while kicking inside a dome.

That said, sometimes it’s better to be lucky than good. While the Vikings aren’t a perfect football team (the Ravens did whatever they wanted in the second half offensively, exposing some of the Vikings’ defensive issues), they have a perfect record and that’s the only thing that matters at this point.

Oh, and having No. 4 under center certain helps too.
