That year, Rypien amassed over 3,500 yards and 28 touchdowns with only 11 interceptions while being sacked only seven times the entire season. This anecdote suggests that the offensive line has a significant impact on an offense, but there is no performance metric that allows us to compare the linemen or understand their true value to a team. The central obstacle to creating this metric is the lack of data on the performance of individual offensive linemen. To address this, we have collected play-by-play data including number of defensive players rushing the QB, time in the pocket, success of each individual linemen, steps in the QB\u2019s dropback, formation and other relevant data. The binary success data is then used in a Cox regression to first establish a baseline probability of success for each position on the line. Once the baseline was established, the regression was run separately for each lineman, allowing each player\u2019s performance to be compared to the average after controlling for time in the pocket. The difference between a player\u2019s performance and the baseline is an estimate of the value added\/subtracted to the team\u2019s passing game.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESpeaker\u0027s Bio:\u003C\/strong\u003E\u003Cbr \/\u003EProfessor Alamar is the founding editor of the Journal of Quantitative Analysis in Sport, a professor of sports management at Menlo College and the director of basketball analytics and research for the NBA\u0027s Oklahoma City Thunder.
