9. Tennessee Titans
Tennessee rode their mean offensive line to a cinderella run in the 2019 playoffs. While Derrick Henry and the rushing attack got most of the attention (they averaged the third-most rushing yards per game), the Titans were also brilliant in pass protection. Football Outsiders says they had an adjusted sack rate of just 4.9%, which was the fourth-lowest in the league. Losing Jack Conklin is going to hurt, though.
