There is no question that when healthy, Chris Kuper is one of the best guards in the league. But that has been the problem.
After being injured in the season finale in 2011, Kuper went on to play in just seven games for the Broncos in 2012, starting just five. This forced Manny Ramirez into the lineup more than Denver probably would have liked.
Ramirez didn't play terribly, but he wasn't exactly great either. Because of this, the Broncos may look to sign an experienced player who can come off the bench and spell Kuper a little bit better if necessary.
So who might the team be looking at?
Kevin Boothe is a 6'5" veteran who has spent the last six seasons as a member of the new York Giants, winning two Super Bowls with them. He is an unrestricted free agent.
Doug Legursky is a very versatile player who can come off the bench and play just about any position on the offensive line, but he excels at guard and center. He is one of those players who does the little things well. Legursky and the Steelers' starting right guard, Ramon Foster, are both unrestricted free agents, so they may not bring both back.
Legursky would be an excellent backup for the Broncos.
