The New England Patriots had some depth issues on the offensive line last season, exacerbated by some injuries throughout the course of the year.
Left tackle Nate Solder's torn pectoral muscle was the first domino to fall, and from there, things came unraveled with a mix of Marcus Cannon, Cameron Fleming, LaAdrian Waddle and even center Bryan Stork starting at tackle.
That being said, injuries aren't the Patriots' only concerns. The 2016 season is the final year of right tackle Sebastian Vollmer's contract, and who knows if the Patriots will be thrilled to re-sign a 32-going-on-33-year-old lineman with a history of injuries and back problems. It's also the final year of Cannon's contract extension, which was signed at the end of the 2014 season.
Whether it's a starter or a backup, now might be a good time to start searching for new players to step into the stable of linemen.
