The offensive line has long been a source of dismay for Lions' fans, but did play well last year. Only half-dozen teams in the NFL allowed fewer sacks. With pedestrian running backs and backup quarterbacks, the Lions nonetheless ran the ball surprisingly well in a few late-season victories.
Offensive line wasn't a priority in the draft, nor has it been in free agency. While it would hardly be considered a strength, it wasn't viewed as a weakness, either.
Then, days before the lockout ended, it was revealed long-time starting left tackle Jeff Backus has an injured pectoral muscle. His status for beginning the season is up in the air. Also, right tackle Gosder Cherilus hasn't been able to practice fully because of a knee injury.
Yes. It's early in training camp.
But yes, it should be a concern.
Do the Lions have enough offensive line depth? It's a fair question that will be answered during the preseason. We'll see if Jason Fox is the answer. Obviously, this is his shot.

- A key for the Tigers is Daniel Schelerth. He and recently-acquired David Pauley must be able to eat up innings at the back end of the bullpen for the Tigers to start pulling away in the A.L. Central.
Schelerth has a good arm. He has plenty of innings and experience under his belt. It's time to stop being a prospect and become a legitimate major league pitcher.
