ALLEN PARK -- The Detroit Lions' offensive line has become a turnstile this offseason.
First Larry Warford bolted in free agency, and then Riley Reiff followed him out the door. Detroit replaced them by signing Rick Wagner and T.J. Lang -- but then lost Taylor Decker in OTAs. He's going to miss at least the first month of the season with a torn labrum, and it's possible he'll be out until December.
Throw in the brewing job battle at left guard, and suddenly, the man who once looked like he could be on the way out of the lineup -- center Travis Swanson -- is its closest thing to a constant.
