It's no secret that the Vikings need help in their linebacking corps. Yes, the team brought Erin Henderson back Tuesday, signing him to a two-year deal. But there's still a void up the middle of the defense. And last year's starter, Jasper Brinkley, spent Wednesday in New York with the Giants and was then off to visit with Arizona, according to USA Today's Mike Garafolo.

So where might the Vikings be turning next to solidify the middle of their defense? A report this evening from Mike Mulligan in the Chicago Tribune says the Vikings could be at least window shopping as Urlacher looks to find a team with which to play his 14th season.

Writes Mulligan:

Urlacher is looking for a deal in the range of the $5.5 million Ray Lewis earned in his last season with the Ravens, a source said. It's unlikely the Bears would pay that type of money and not responding to the offer may be a less-than-subtle way of avoiding an embarrassing negotiation.
Urlacher can't be thrilled but Emery does not believe Urlacher feels slighted by "the process," something the GM vowed to avoid when he last talked about the subject last month.
Is Urlacher interested in wearing purple or is he just trying to create a market?
Urlacher has been a fixture in Chicago since the Bears drafted him with the ninth overall pick in 2000. He's an eight-time Pro Bowler and a future Hall of Famer. But he's also about to turn 35, in the twilight of his career, missed four games last season with a hamstring injury and doesn't exactly seem to fit the vision Vikings General Manager Rick Spielman has for building his roster.

Spielman continues to talk about building through the draft while making a few practical, good-fit investments in free agency. Urlacher would seem like an odd piece to the puzzle under that plan, a mere quick fix for a team that would likely prefer to find a longer-term solution. Sure, he might have some game left and would need little time to get up to speed with the Vikings' defensive system.

But a day after letting 35-year-old cornerback Antoine Winfield go as a means of saving $7.25 million, it would seem odd to turn around and deliver a major contract to Urlacher.

Perhaps the Vikings are keeping themselves in the talks for Urlacher as a means of stretching Chicago GM Phil Emery's financial plans a little thinner. Emery and the Bears, after all, showed significant interest in right tackle Phil Loadholt as free agency neared. And in a determined effort to keep Loadholt, the Vikings needed to deliver a four-year $25 million deal.

That's a small part of the game during free agency -- looking for ways to get better while also scheming for ways to put stress on division rivals.
