Eagles rebuilding on the fly?

Posted by ESPN.com's Matt Mosley

I have a quick layover in Houston en route to New Orleans, so I'm catching up on a little NFC East reading material while downing a suspect turkey and mushroom burger. Frequent Beast contributor Adam Schefter had an interesting nugget in his 10 Spot column today on how the Philadelphia Eagles have rebuilt their offense without having to go through serious growing pains:

The Eagles have been successful for years and yet they've turned over their roster with most barely noticing. When the Eagles played the Chiefs on Sept. 27 and scored 34 points, the average age of Philadelphia's starters on offense was 24.5 years. The unit featured Jeremy Maclin (21), LeSean McCoy (21), DeSean Jackson (22), Brent Celek (24) and Kevin Kolb (25). In fact, Jason Peters (27) and Jamaal Jackson (29) were the offense's graybeards. In other words, the Eagles' offense is built for the long haul. But it also is built for now. Through four games, the Eagles have averaged 31.75 points. At this rate, Philadelphia would score 508 points -- 92 more than the season franchise record 416 that the Eagles scored last year. This is a novel concept in places such as Oakland and Cleveland, but this team rebuilt without ever going through any of the real suffering.

Of course, the presence of Donovan McNabb and Brian Westbrook give the Eagles an older look -- but Adam hits on an important point. The Eagles have continued to field a competitive each year while re-making the offense. And something that's not talked about enough is how good a job the Eagles have done at developing young offensive linemen. The presence of players such as Nick Cole and Max Jean-Gilles have allowed the Eagles to get through some tough spots in terms of injuries.

The Redskins have shown us what happens when you don't put a premium on creating depth along the offensive line. I believe they may be fielding the worst offensive line in the league Sunday against the Chiefs.
