The Baltimore Sun reports that Scott is only $400,000-$700,000 apart with Baltimore in contract negotiations.  That tells me he's unlikely to fly the coop.

Brown, on the other hand, is reportedly far apart in discussions.  Brown is my top offensive lineman available, and one of the top-five at any position.  It's rare to see difference making offensive lineman available at any position, and he has versaitility.  Any team serious about the running game will want him.  Washington, Miami, St. Louis, and Kansas City have been mentioned as suitors for Brown. 

If Scott re-signs today, one has to wonder if Ray Lewis will start taking free agent trips this weekend.  Even if he doesn't sign elsewhere, visiting a team like the Jets would increase Lewis' leverage.
