When you have great players, scheme is less important than execution. Defenses knew Donovan McNabb was throwing the ball to Terrell Owens in 2004. That didn't matter and the Eagles' offense put up a lot of points. The 2006 team fed the ball to Brian Westbrook. Defenses struggled to stop him and the Eagles finished second in the NFL in yards. The 2010 team had Michael Vick handing the ball to LeSean McCoy and throwing it to DeSean Jackson and Jeremy Maclin. That team finished third in the league in points.
We honestly don't know what to expect from the 2017 offense.
