There is absolutely no guarantee that Chris Cook or Antoine Winfield would have made a lick of difference against the shockingly efficient Aaron Rodgers on Sunday, but the absence of the Vikings' top two defensive backs exposed just how painfully weak the Vikings' secondary really is.

Cornerback Cedric Griffin is a mere shell of the player he was prior to blowing out his knee (the first time) in the 2009 NFC Championship game. He's lost at least one step per ACL surgery (two in total), appears to be completely devoid of confidence, and should no longer be considered a starting-caliber player. Problem is, the Vikings don't have anybody better.

I can't think of (or find evidence of) anything that Asher Allen does that's better than your average street free agent. Safety Husain Abdullah has been the culprit on two separate back-breaking touchdown bombs in the last two weeks alone. The other Week 7 starting safety, Tyrell Johnson, was, until Sunday, playing behind a former seventh-round draft pick who isn't very good either (Jamarca Sanford).

Perhaps the most troubling aspect of the porous secondary is that the Vikings have attempted to address the situation via the NFL Draft repeatedly. They just haven't done a very good job.

Dating back to 2006 (Griffin in Round 2), the Vikings have burned five picks within the first three rounds on defensive backs.

Tough to blame anything but bad luck on Griffin, who was developing into both a sound tackler and an excellent cover corner just before the fateful overtime kickoff in the 2009 title game on which he blew out his knee for the first time.

But after that, it gets ugly. Third-rounder Marcus McCauley (2007) started nine games in his rookie season before being benched and then released after the 2008 season, then playing in one game for the Lions in 2009 before his brief career came to a merciful end.

In 2008, Tyrell Johnson was chosen in Round 2. Johnson started seven games in his rookie season and 15 games in 2009 before being benched in favor of mega-bust Madieu Williams and the undrafted Abdullah in 2010 and losing a training camp battle to Sanford this year. For the record, Pro Football Focus (PFF) grades Abdullah as the 74th-"best" safety in the NFL (out of 90 that have earned a grade by PFF's game charters) this year in terms of pass coverage. Sanford (82nd) and Johnson (85th) are even worse.

Allen, a third-rounder in 2009, was burned repeatedly when forced into action in the place of an incarcerated Cook on Sunday. According to PFF, Rodgers threw Allen's way 10 times, completing nine of them for 108 yards. Of the 98 cornerbacks that have been ranked by PFF this season, only five have graded out worse than Allen in pass coverage.

Which brings us to Cook, the 2010 second-rounder (after trading out of Round 1) who has garnered attention far more for his off-the-field antics than anything he's done on it. In fairness to Cook, he's actually been playing very well this season. He's been used to shadow elite receivers from Vincent Jackson to Calvin Johnson and held up remarkably well. According to Pro Football Focus, Cook has allowed 60% of the passes thrown in his direction to be completed, but he's done a very good job limiting the damage to just 187 total yards and one touchdown in just over four games.

Then again, judging character is just as important as judging skill, and the early returns indicate that the team may not be able to depend on Cook, no matter how well he plays when he's in uniform, in the short or long-term.

The absence of Winfield really can't be overstated here. He's been PFF's No. 1-ranked cornerback twice in the last four years (and hasn't dropped out of the top 12 in the same span), and despite getting older and becoming increasingly injury-prone, the secondary is completely different when he's not on the field.

With a healthy Winfield and an unjailed Cook, things wouldn't look quite so dire, but the safety situation is nothing short of disastrous, and both the unbearable lack of talent at safety and the lack of depth at cornerback is directly traceable to the inability of the front office to land NFL-caliber starters in the draft, despite using high picks in an attempt to do so.
