The San Francisco 49ers are not afraid to window shop.They continued that approach with a recent visit with cornerback Brandon Flowers. Fox Sports 1 reported that Flowers visited Friday with the 49ers. He agreed to terms Tuesday with the San Diego Chargers, the first team with whom he visited . He was recently cut by the Kansas City Chiefs.I'm not surprised by the 49ers' interest, but I am also not surprised that they didn't do enough to pluck Flowers away from San Diego.
