Pro Football Focus assigned Bell a grade of negative 12 for the 2011 regular season, and one of the worst players on the Miami Dolphins defense. Opposing quarterbacks had a cumulative quarterback rating of 105.5 when throwing at Bell last year. He had four pass deflections, along with an interception. He was only thrown at 40 times, but allowed 26 catches for 333 yards and three touchdowns.
Bell is however consistently rated as one of the better tackling safeties in the NFL with over 100 stops in each of the last four seasons.
