Detroit, the Chargers, Houston, and Philadelphia changed their offensive lines

Detroit is switching tackles, adding a rookie, and sorting a new center. The Chargers return their tackles and have three new interior options. Houston overhauled the line in front of C.J. Stroud. Lane Johnson described Philadelphia's new blocking approach.

This board follows four distinct line changes in Detroit, Los Angeles, Houston, and Philadelphia. The useful question is not whether a team added names. It is whether the group can stay healthy, settle its positions, and execute the new blocking plan.
