Detroit Lions offensive line is a work in progress a year after being among NFL’s best
The Detroit Lions had one of the NFL’s best offensive lines last season. This year is more of a work in progress. Center Frank Ragnow’s retirement and the loss of right guard Kevin Zeitler in free agency have opened up competition for at least two new starters. Graham Glasgow, who started at left guard last season and has experience at center, along with rookie Tate Ratledge are getting reps at center through four days of training camp. And then there’s the banged-up veteran Taylor Decker at left tackle.
