A few days ago, I looked at what kind of window of opportunity the Vikings had for a serious championship run.  Today, I want to continue down that path with a look at the defense.

DL:

Pat Williams, 37

Kevin Williams, 28

Jared Allen, 27

Kenechi Udeze, 26

Fred Evans, 26

Jimmy Kennedy, 30

Brian Robison, 26

Ray Edwards, 24

The Vikings defensive line is almost as dominant as the halcyon days of the legendary Purple People Eaters.  You don’t run on them, and quarterbacks drop back to pass at their own risk. They are at least as effective as the Keith Millard-Chris Doleman defensive lines of the early 1990’s, but the anchor of the line, Pat Williams, is going to be 37.  This line didn’t become dominant until ‘Phat Pat’ was signed, and it became elite when the Vikes traded for Jared Allen.  Pat Williams seems ageless, but he isn’t, and the Vikings need to look towards his eventual replacement.  There isn’t another Pat Williams currently on the roster, so something will need to be done.  When he is out of the lineup, the Vikings are not dominant as a run defense.  The rest of the line is in their prime, and if Kenechi Udeze can get back his strength and quickness, he will be a force in 2009, and will take this defensive line to another level.  Kevin Williams and Jared Allen have at least 5 more years playing together at an elite level; throw in a healthy Udeze, and these guys will be a lot of fun to watch.

Projection:  1-2 years, as the next Pat Williams needs to be identified.  If the Williams transition is seamless, 5-7 years of high end productivity.

LB:

Chad Greenway, 26

EJ Henderson, 29

Ben Leber, 31

Heath Farwell, 28

David Herron, 25

 The front line starters for the Vikings are one of the best LB tandems in the NFL.  They complement each other well, and are a solid mix of youth and veteran leadership.  But the replacements currently on the roster are not considered NFL-caliber starters, as the signings of ex-Vikings Napoleon Harris and Dontarrious Thomas showed.  Ben Leber is north of 30, EJ Henderson is approaching 30 and has an injury history, and Chad Greenway has developed into a quality NFL LB after a season ending knee injury as a rookie.  I thought that LB would be addressed early in the 2009 draft, but you can’t argue with Percy Harvin and Phil Loadholt.  LB’s can be had in free agency, and it should be a position of need next year in the draft.

Projection:  2 years, but they need depth right now.  Not re-signing Harris or Thomas could turn out to be a big mistake if one of the top three goes down.

DB:

Antoine Winfield, 32

Cedric Griffin, 27

Marcus McCauley, 26

Tyrell Johnson, 24

Madieu Williams, 28

Karl Paymah, 27

Asher Allen, 21

I love Antoine Winfield.  I mean, I started a blog called The Purple Buckeye, for God Sakes.  Winfield has been a mainstay in the defensive backfield, and has been the best all-around CB in the NFL for about his entire time in Minnesota.  I hope he retires a Viking, but with contract extension talks stalled, that seems up in the air.  But he’s north of 30, and the Vikings used a third round pick on Asher Allen, so Minnesota is laying the groundwork for Winfield’s eventual replacement.  The Vikings wisely inked Cedric Griffin to an extension, meaning that his productive years will be spent as a Viking.  For the safeties, Tyrell Johnson has already taken over for Darren Sharper and will be a fixture for several years, and Madieu Williams has 3-4 years of above average production left.  Overall, this unit looks pretty good, as long as Allen can get close to the level of THE Antoine Winfield, a tall order indeed. 

Projection:  Winfield will probably be replaced after 2009, 3-5 years after that. 

There is no need to raise the alarm yet, but the defense, which has done most of the heavy lifting on this team during the Brad Childress era, is the side of the ball where the window opening is currently the smallest.  The line, linebackers, and defensive backfield will need to be addressed, both for front-line starters and depth, especially in the linebacking corps.  If the starters can stay relatively healthy in 2009 and 2010, this defense, with a ferocious defensive line that can neuter a running game and punish a quarterback that dare try to pass, can take this team a long way.  But Ben Leber, Antoine Winfield, and Pat Williams, key veterans that made this defense what it is, will be replaced in the next few years, and who comes in behind them will largely determine how competitive the Vikings will be. 

Along with the play of the quarterback.
