2012 NFL free agency primer: the offensive linemen

The Ravens would like to improve their offensive line during the offseason, but the best move they could make in free agency would be re-signing Ben Grubbs, who could soon be one of the top guards available. The Ravens recently said that they have already offered big money to Grubbs -- and there’s no reason not to believe that claim -- but if Grubbs, who turns 28 this month, hits the open market, he could be gone for good.
