How you feeling? Eagles-Bills

As you get ready for the Philadelphia Eagles' game Sunday afternoon in Buffalo, here is one reason for Eagles fans to be feeling good about the game and one reason for concern:

Feeling good: Well, the Eagles should be able to generate some offense. The Bills are ranked 25th in the league against the run and 25th against the pass, so this is an opportunity for Philadelphia to showcase all of its great offensive weapons if it chooses to do so. The absence of left tackle Jason Peters, who's out with a leg injury, likely will force the Eagles to try a variety of things on offense and mix things up better than they did last week, when Michael Vick was throwing deep all day and running back LeSean McCoy was a non-factor. I'd expect a lot of McCoy, either running or catching the ball, and for Vick to take some shots downfield, though not quite as many as last week. Variety could be the key to keeping the Bills off-balance and keeping Buffalo's offense off the field.

Cause for concern: This one's easy. The Bills have the fifth-best rushing offense in the league, running for 137 yards per game. The Eagles have the third-worst rushing defense in the league, allowing 139.5 yards per game on the ground. Buffalo's Fred Jackson is one of the most dangerous running-back threats in the league. He ranks fourth in rushing yards with 369 and has caught 13 passes for another 147 yards in the air. Buffalo's air attack is nothing to sneeze at, but the Eagles are going to have to focus extra attention today on the run game and hope their great cornerbacks can cover the Buffalo receivers while the rest of the crew focuses on stopping Jackson.
