Center Olin Kreutz is leaning towards retirement after negotiations with the Chicago Bears fell through over the weekend. The Bears gave Kreutz and his agent an ultimatum on Saturday for a one-year, $4-million contract, which was a 50-percent cut from what he made last season. After that was rejected, Chicago moved quickly to sign former Seattle center Chris Spencer, which signals the possible end to the 13-year career of Kreutz.
