The Browns have signed G/C Rex Hadnot to a 2-year contract.  The 26-year old Hadnot is a massive, physical player at 6′2″, 325 pounds.  Hadnot will likely move into the starting lineup as long as he can beat out Ryan Tucker.  He started all 16 games last season for the Dolphins.  He has now played in 63 games (55 starts) in his 4-year, NFL career.  The Browns have done a great job of filling needs this off-season and Hadnot was another nice piece to add to the puzzle.
