Barksdale or any other starter in the NFL is not unknown. Every team has a pro personnel department whose sole purpose is to grade and rank every player in the league. While the Rams will obviously know more about him, other teams will have an opinion on him. The question will be how they value him. There is no way to know that. It only takes one team who really likes him to drive up his price. There will also probably be few quality O linemen available in free agency so that too could drive up his price. I wouldn't count on getting him for a discount....but you never know how these things will play out. If he does get away they have 3 holes on the O-line.
