To those asking for specific solutions: OP is not a general manager. There are about 180 guards (just guards, not just offensive linemen) in the NFL, and that doesn't include practice squad players. Fans do not have the resources to do the work of a general manager. A general manager has the resources to investigate which ones would be a scheme fit, which are viable trade candidates, and which are in favorable contract situations. Out of 180 players (plus many more on roster bubbles) I highly doubt that there are zero available to us. Beane likely has a list of appropriate targets. I'm hoping he's just waiting for roster cuts to see if any on his list end up on waivers, but he needs to address the situation one way or another.
