Just when the 49ers think they’ve found their center for the future, he goes and becomes a free agent. Such is the case of David Baas, who was an inconsistent guard for his first five years in San Francisco before switching to center last year when starter Eric Heitmann went down with a broken leg early in training camp.
The 49ers haven’t scheduled any visits with college centers, which may be a signal that they believe they can re-sign Baas and/or backup Tony Wragge when the free-agency period begins. If not, there are a few mid-round prospects such as Wisconsin’s John Moffitt, who can fill back-up positions at both guard and center. Heitmann wants to see whether an offseason of rest will solve the problem, but there is a very real chance he will retire instead of play his 10th season.
