6. Philadelphia Eagles
The fastest offense in the league, Philadelphia lost its downfield threat in DeSean Jackson, and is relying on oft-injured Jeremy Maclin to regain his form in his place. The catalyst here is rookie Jordan Matthews, who has been the talk of the Eagles offseason. Zach Ertz, too, is poised for a breakout campaign. But we all know the straw that stirs the drink is LeSean McCoy, who has the explosive Sproles to spell him.
