It may surprise you to find out that the Detroit Lions offensive line allowed only 29 sacks last season, just three more than the No. 3 ranked New Orleans Saints. They also graded out as the No. 3 offensive line in pass blocking by Pro Football Focus. PFF ranked the Lions 18th in run blocking in 2012, based on their grading system, which may also seem surprisingly high, considering their inability to establish a rushing game last season.
