The Bills choose to lock restricted free agent Marques Sullivan up long term by signing him to a multi-year deal and preventing any other team from even making an offer to him. Sullivan, who started all 16 games for the Bills at right guard in 2002, is expected to be in the mix to replace Ruben Brown at left guard. “Marques started here for a year and played pretty well two years ago,” Tom Donahoe said on Monday.
