The two teams at the extreme ends of the offensive line continuity scale last season both played in the NFC West. One of them achieved continuity perfection and went on to play in the Super Bowl. The other went through an unprecedented number of starters and finished with the worst record in the league.
Offensive line continuity scores were originally developed by Jason McKinley in the early days of FO (when FO Almanac was still Pro Football Prospectus) and we have since gone back and calculated it for every team since 1999. The continuity scores are based on three variables: number of starters used; number of week-to-week changes in starting lineups; and the longest starting streak of any one five-man unit.
