They’ll lean on offensive coordinator Hank Fraley, the mastermind behind the group. Lineman Penei Sewell is already one of the best leaders on this team. Graham Glasgow is another veteran who can set an example for the young interior linemen. And then there’s Decker, who often doubles as the voice of reason when doom and gloom trickles in.

Detroit's offensive line faces more questions than it has in years, with Frank Ragnow retiring and Kevin Zeitler departing in free agency, leaving a massive hole on the interior.

Glasgow is the biggest offensive line health concern heading into the season. A reliable, solid player for most of his career, his performance dipped last season possibly due to knee injuries. He was listed twice with an unspecified knee last season and missed one game due to it. There was no specific injury seen on video last year.
