Daunte Culpepper dived into the end zone for a touchdown, then rose, tapped his surgically repaired right knee and signaled "OK" to the crowd. His much-scrutinized knee might not be 100 percent, but it was good enough Sunday for Culpepper to lead the Oakland Raiders past the Miami Dolphins. He ran for three touchdowns and threw for two to win the grudge game against his former team, 35-17. Culpepper led the Raiders out of the tunnel before the game, raising his right fist and punching the air as fans booed. He was hardly flashy against his old team, relying on a ground game that totaled 299 yards against an injury-depleted defense.
