BALTIMORE -- There should be a new unwritten rule in the NFL: Never make a mid-game quarterback change from a veteran to an inexperienced backup against the Baltimore Ravens' defense.
The Philadelphia Eagles went against conventional wisdom and paid for it dearly Sunday during a 36-7 blowout defeat to the Ravens. Eagles coach Andy Reid benched starting quarterback Donovan McNabb (two interceptions, one fumble) at halftime with the Ravens leading 10-7.
Second-year backup Kevin Kolb (two interceptions) came in and struggled mightily, as a three-point deficit at intermission quickly ballooned in the second half. The final nail was a 108-yard interception return by Ravens safety Ed Reed that was the longest in NFL history.
While the Eagles (5-5-1) are surely in turmoil, the Ravens have continued their stability this season. Baltimore is now 7-4 with a chance to further pad its record next week against the Cincinnati Bengals (1-9-1).
