How you feeling? Eagles-Cardinals

As the 2-0 Philadelphia Eagles prepare to face the 2-0 Arizona Cardinals at 4:05 p.m. ET today in Phoenix, here's one reason for Eagles fans to feel good and one reason for concern.

Feeling good: Arizona's 2-0 start has a lot more to do with the play of its impressive defense than anything it's been able to do on offense. And with backup quarterback (and former Eagle trade chip) Kevin Kolb under center, the Cardinals should struggle to score enough points to beat the Eagles. Philadelphia's defense has played at a very high level so far this year, and it's the main reason the Eagles have been able to win two games in spite of the nine turnovers they've committed. As long as Philly can get wide receiver Larry Fitzgerald covered, the Cardinals have very few other offensive weapons with which to hurt them.

Cause for concern: This is not the place for the Eagles to go to solve their turnover problems. The Cardinals' defensive front should do a good job of putting pressure on Eagles quarterback Michael Vick, who is prone to mistakes and poor decisions when under pressure. The Eagles also are playing without starting wide receiver Jeremy Maclin and starting center Jason Kelce, and camp disappointment Demetress Bell is starting at left tackle in place of the injured King Dunlap (who'd been starting in place of the injured Jason Peters). At some point, the Eagles won't be turning the ball over 4.5 times per game anymore. But especially if the Cardinals can win up front and limit LeSean McCoy and the run game, it could be tough for the Eagles' offense to get on track today.
