San Francisco 49ers general manager John Lynch was on KNBR Thursday morning discussing a few personnel moves on the team. Let’s start with cornerback. Lynch wouldn’t come out and say that Emmanuel Moseley won the starting cornerback position. Lynch said Moseley, “impressed us. He showed even more than last year.” Lynch noted that Jason Verrett tweaked his hamstring at practice on Wednesday. The team is awaiting the results to see how bad the injury is. Matt Barrows said it’s a Grade 1 strain, which is the lowest level.
