There are also reports from Rapoport though that Linderbaum's camp isn't returning the Ravens calls. DeCosta is saying the right things and I don't doubt that the Ravens want to retain him (otherwise they are replacing their entire IOL this offseason).
At this point, for whatever reason (whether money, hard feelings at the Harbaugh departure, or otherwise), I think he's going to hit the open market. Does he take $21MM to go to Browns, Jets, or Titans over $19MM to return to the Ravens? I doubt it. But if it's the Seahawks, Eagles, or Lions who are willing to pony up, it might happen.
If the Lions can somehow swing it, he is the closest thing to Frank Ragnow that's not Frank Ragnow.
