The New England Patriots offensive line during Thursday night's preseason opener versus the Houston Texans -- a group that mostly consisted of backups -- gave a lackluster performance.
It certainly wasn't an encouraging sign for the Patriots, especially given the o-line's struggles over the first few weeks of training camp. If any of the starting offensive linemen miss games with injuries this season, it's unlikely many of these backups would step in and play at a high level.
So it wasn't much of a surprise to learn that New England brought in two free agent offensive linemen for tryouts Friday.
