By tomorrow afternoon, the Ravens will either have their replacement for Jason Brown or the Vikings will have brought back the elder statesman of their offensive line. Matt Birk says that his first jump into free agency won't take long, as he'll make a decision by Thursday on whether to sign with the Ravens or return to Minnesota.
The Ravens need Birk more than the Vikings do. Minnesota has been planning for Birk's potential loss, as they are grooming John Sullivan to replace Birk, although there is little doubt that Birk, a six-time Pro Bowler, will be a better center in 2009 than Sullivan.
