Philadelphia ? Philadelphia expects to win a Super Bowl in less time than it took to win the NFC championship.

Playing in their first Super Bowl in 24 years wasn’t enough for the Eagles. They want to come back and win it — quickly — after losing, 24-21, to the New England Patriots on Sunday.

“We’ll get over it,” coach Andy Reid said Monday. “We’ll get through this thing, and we’ll come back and learn from it.”

Getting back certainly won’t be easy — just ask the NFC teams that played in the Super Bowl this decade.

Carolina’s repeat bid was sidetracked by a slew of injuries, and it failed to make the playoffs this year. Tampa Bay (2003) was the first team to follow a Super Bowl victory with consecutive losing seasons, and neither St. Louis (2002) nor New York (2001) has returned to the conference championship game.

“I do understand the history of that, and I know it’s a tough thing,” Reid said. “The reason I think we can get back here is we have a great nucleus of young players who had a taste of this thing.”

Maybe that’s what separates the Eagles from so many of the other teams. In this salary-cap, free-agency era, Philadelphia (15-4) seems built to last.

They have $18 million available to spend, and most of their best young players are signed to long-term contracts.

Corey Simon, Jermane Mayberry, Jeremiah Trotter, Derrick Burgess, Chad Lewis and Jon Ritchie all are unrestricted free agents, but only losing Trotter would be particularly damaging.

“You want to think there will be subtle changes, but you never know how it works out,” Reid said.

The Eagles made a big splash in the free-agent market last year, signing Jevon Kearse, Hugh Douglas and Trotter, and trading for Terrell Owens.

Owens led the Eagles with 77 catches for 1,200 yards and 14 TDs, then made a stunning return to play in the Super Bowl just 61/2 weeks after ankle surgery. He invigorated the Eagles with his swagger and delivered everything expected, from the electric playmaking to the outrageous antics — including a steamy segment with actress Nicollette Sheridan for the intro to “Monday Night Football.”

Reid and team president Joe Banner have a history of adding quality on draft day, too.
