Looking forward to a grand finale to the 2012 regular season when the Packers pay a call on Mall of America Field Sunday to meet the Minnesota Vikings in a game with profound playoff implications.   The Packers of course, are already in, having secured a second straight NFC North title two weeks ago in Chicago.  A victory at the Metrodome would lock up the number two seed in the conference, secure a first round bye and establish a little history as the Packers seek to sweep their division rivals for a second straight season.  That's never happened since the league went to its current division format.  As for the Vikings, a three game winning streak since the 23-14 loss at Lambeau Field on December 2 has them in position to clinch a wild card spot with a victory.  A loss would require outside help, namely from Detroit beating Chicago, Dallas losing to Washington and the Giants falling to Philadelphia.  It will be a highly charged atmosphere, maybe the most intense game in the series since the ol' gunslinger switched allegiance to the purple and gold three years ago. The rush for the record is also a part of the drama.  Adrian Peterson's remarkable season has him at 1898 yards, 102 away from becomming just the seventh back to reach 2000, and he's 208 yards away from breaking Eric Dickerson's single season rushing record of 2105.   Need I remind you, Peterson ripped through the Packers for 210 yards in the first meeting earlier this month.  Earning a week off and denying Peterson the record offers plenty of motivation for the Pack.  To get it accomplished, they'll have to tackle better, more than 10 missed tackles in the first meeting when Peterson piled up runs of 82, 48 and 23 yards.   The big bodies up front will have to tie up blockers, the linebackers must be disciplined in filling gaps and there had better be more than one or two hats on number 28 at all times.  Success on early downs will force the Vikes to turn to second year quarterback Christian Ponder to make plays in the air.  Playing with a lead could also limit Peterson's touches.  Ponder floundered much of the year but has turned the ball over only once in the last three weeks after a pair of disastorous interceptions at Lambeau.  Without Percy Harvin, the Vikes have limited weaponry outside.  Tight end Kyle Rudolph is the go-to guy now and there's been little help from the wide receivers all year.  A bigger reason the Vikes are in playoff position is the play of their defense.  The unit held Houston without a touchdown on their home field last week.  They can pressure without blitzing so it will be a big day for Evan Dietrich-Smith in his second career start at center, first on the road, against a riled up front four.  Aaron Rodgers is an expert at recognizing and avoiding the heat and if Randall Cobb's ankle sprain heals, the reigning MVP will have his full compliment of receivers for the first time since early October.  The Packers run game has also come to life of late, they attacked the Minnesota flanks in the first meeting, with James Starks scoring on a 22 yard stretch play outside.  Don't forget the 18 play, 73 yard and 11 minute drive that all but sealed the victory.  If Peterson is slowed down at all, I'm hard pressed to believe Ponder, in the biggest game of his fledgling career, can make enough plays to win.  Let's take Green Bay for the 2 seed clincher, 26-20.  On the link below, quotes from the Packers and the Vikings on what should be an epic, if not grand finale.
