The Kansas City Chiefs defense comes up with a bad reputation against the Philadelphia Eagles. The last time these two teams met, the Eagles offense torched the Chiefs for 420 yards of total offense and 34 points. There's no doubt some of the Chiefs on this team remember that game.
How the linebackers play will be a big part of this game. The Eagles offense includes lots of passing and not necessarily a lot of deep passing. There are 10-15 yard plays over the middle of the field that they consider high-percentage. The linebackers need to A.) get after the quarterback and B.) be strong in coverage. Sacking the quarterback may be the biggest challenge for this defense but doing the other things, like pass coverage, is a must for a defense that was nearly last in 2009.
The defensive line is also under the microscope, maybe more so than any other position group. The good thing is that the Eagles offensive line may not be in the best of shape, which could inspire some confidence along the Chiefs defensive line. If I may steal from mushin's latest post:
The Eagles offensive line was manhandled last weekend by the Bengals. They gave up 3 sacks and 4 tackles for a loss. At least two of the 4 interceptions from the Eagles backup QB's came as a direct result of QB pressure. The only positive the Eagles can take away from the game is that they don't track QB pressures and hurry up stats in the preseason.
The secondary is another area that will be tested against the Eagles, who have passed for the second most yards in the NFL at this point in the preseason. Kevin Kolb is on his way to becoming an elite quarterback so, if the Chiefs can provide some sort of pass rush, it'll be interesting to see how the secondary does against a first-rate pass offense.
Bottomline, the Chiefs need to contain the Eagles pass offense. They're also first in the NFL in rushing yards right now but their strength is passing the ball. I can't say I expect much pressure out of the Chiefs front seven but I do expect the secondary to limit the big plays.
