SANTA CLARA (AP) — The San Francisco 49ers are ready for some serious chatter coming from that brash, big-talking Seattle secondary.And 49ers fullback Bruce Miller insists cornerback Richard Sherman and the playoff-bound Seahawks (11-1) have more than earned the right to speak up on the field.“So far they have a reason to,” Miller said Tuesday. “They’ve played great on defense and we’ll just have to take care of that in between whistles.”The way emotions tend to run higher than usual in this heated NFC West, Miller, tight end Vernon Davis and their teammates are guarding against getting so hyped up it hurts the cause. Jim Harbaugh also appreciates the energy and physical play by his guys, along with proper celebration on big plays — such as wideout Anquan Boldin flexing his muscles and cheering when he makes a clutch reception.“It might be the most intense game this season.
