The Eagles remain an enigma.
The defense takes a lot of chances with blitzes, which have been pretty successful. The defensive line rotation has been incredible, keeping the players rested. Other than Dawkins and Sheldon Brown, the secondary can be very suspect at times (horrible play on 4th an 18). The LB are nothing special outside of Trotter. The biggest defensive problem reamins that they are susceptible to giving up big chunks of yardage against rushing teams. Andy Reids philosphy is to throw early, get a lead, and thereby limit the amount of rushing opportunities the otehr team can reasonably make.
The offense stil revolves arounf Westrook. Donovan was 18-33 yesterday, not incredible completion percentage there. The big yardage cam on dfensive lapses (yes, they pu the Boys in positions to make mistakes, but you cannot count on blown coverages). McNabb only made 2 or 3 really tough throws during the game for completions. And with all of that, the game really should have ended up in overtime (horrible interception by Bledsoe). But I will take the win.
On the 3 point line, I believe the linesmakers are looking at the strenght of the Saints rushing attack, and commitment they have to rushing the ball, ability to get Bush on the edge in coverage with the LB, and the weekly size mismatch that all teams seem to have against the eagles CB. Plus the Eagles cannot run out a clock, so even a 10 point lead late in Q4 has the potential to end up on a 3 given a late TD by the saints.
Hope this helps
