49ers notes: Person of interest in RG competition

A leader has quietly emerged in the 49ers' only competition for a starting job. Veteran offensive lineman Mike Person has not missed a practice since the opening of training camp. "I'd say Mike's been the same guy that we knew of, if not a little bit better," 49ers coach Kyle Shanahan said of Person, who started 14 games at center in 2015 for the Atlanta Falcons when Shanahan was offensive coordinator.
