Miami Dolphins cornerback Vontae Davis blitzed from the blind side for a sack, then dashed upfield in jubilation. A dazed Carson Palmer rose slowly, looked back at Davis and did a double take, as if startled to discover his tackler was a 5-foot-11 cornerback. The Dolphins are full of surprises lately. Once-woeful Miami won for the fourth time in the past five games Sunday by beating Oakland 34-14. Reggie Bush ran for 100 yards and a touchdown, Matt Moore had a hand in two TDs and Kevin Burnett returned an interception 34 yards for Miami's final score.
