Miami ? The last time the Philadelphia Eagles played so well for so long, they won the NFL championship. That was 43 years ago.

Donovan McNabb threw a 59-yard completion on the first play, receiver Freddie Mitchell’s first career completion went for a touchdown, and Philadelphia beat the slumping Miami Dolphins, 34-27, Monday night.

The Eagles extended their winning streak to nine games, matching the franchise record set in 1960, when they went on to the NFL title. Philadelphia (11-3) matched the St. Louis Rams for the NFC’s best record.

“We’re opening up some eyes,” McNabb said. “We’ve gotten better and better each week. Guys are out here having fun.”

The result pushed Miami to the brink of elimination from the playoff race. With coach Dave Wannstedt’s job in jeopardy, the Dolphins (8-6) slipped into their traditional December swoon with a second consecutive loss.

The Dolphins could miss the playoffs for the second year in a row even if they win their final two games against Buffalo and the New York Jets.

“Do we need a little bit of help? Sure,” Wannstedt said. “Anything can happen.”

When asked if he was concerned about his job security, Wannstedt said, “I’m just concerned about Buffalo, to be honest with you.”

Philadelphia has averaged 32 points in the past five games, and McNabb and company continued to roll against a Miami defense that ranked third in the NFL in points allowed.

The 34 points and 401 yards allowed by Miami were season highs. The Eagles scored touchdowns on three of their first four possessions.

“They probably made more big plays today than we’ve given up all year,” Wannstedt said. “We missed too many tackles.”

Three times the Dolphins came from behind, but they couldn’t rally after Correll Buckhalter scored on a 2-yard run with 14:53 left to break a 24-all tie.
