Not sure we would get much if anything. Eric Winston was an unclaimed free agent for a long time before finally getting picked up a couple years ago. I put Free in a similar class. He is considered more of a mid season addition type in most people's minds.
Won't matter because they ain't spending another top pick on the oline. Your never gonna have a pro bowler at every position and you can't tie up that bug a chunk of your cap on one position. We are about to have the highest paid oline in the nfl very soon as it is
