I think more than any other area, the Eagles run defense will decide how successful they are this year.
Here's an interesting article by Dave Spadaro of PhiladelphiaEagles.com about Jim Johnson and the Eagles run defense .
The Eagles will run the football well if they choose to do so. If they run it well they will destroy teams on the ground and in the air. McNabb has an outstanding group of young recievers, who I think will turn heads this year. I've got a lot of confidence in the Eagles offense. But the defense I'm not as sure about. They will destroy teams on 3rd down with their coverage and pass rush but they'll struggle if they can't stop the run, so I consider the run defense, the key to their season.
Jim doesn't plan on making any major changes when it comes to stopping the run. He's going to rely on bigger, better players doing a better job of executing their defensive assignments in order to stop opposing running games. Jim plans on rotating his defensive linemen and he'd better follow through with it. The run defense went into the tank when Johnson stopped rotating his smallish defensive line. If the Eagles defensive line unit gets tired, they'll get destroyed because they're undersized. Andy needs to look over Jim's shoulder and make sure he rotates that line each and every game.
