Yes, we've already listed this competition. But things change quickly this time of the year. With the 49ers' signing of Davis on Thursday, we figured it was worth updating. Daniel Kilgore might see some time at right guard, but he'll also work at center. Rookie Joe Looney has not been cleared to practice, so he does not figure to be involved in the competition. The 49ers signed Davis for one reason: To see if he might be a better option than Boone. Davis has started 155 regular-season games in his career. The 49ers want maulers at their guard positions. They have a powerful force at left guard with Mike Iupati. And that's the reason they had no interest in re-signing athletic Adam Snyder, who started for the 49ers at right guard last season. Davis is feeling healthy after offseason surgery to repair a lingering foot problem. He passed the team's physical and conditioning test on the day veterans reported to camp. Now, the question becomes whether the three-time Pro Bowl performer is better-suited to play right guard than Boone, the converted tackle. Davis is two inches shorter and about 75 pounds heavier than Boone. Finally, there appears to be the possibility for some real competition for a 49ers starting job during training camp.
