The two changes that must be made are at wide receiver and linebacker. At minimum, the Eagles need to add size at both positions. The receiver needs to be a big red-zone target, like Plaxico Burress, because giving quarterback Michael Vick that kind of weapon in close to the goal line is crucial. The linebacker needs to be able to play credibly on first down, and have the heft to deal with the guards who are going to be in his lap for as long as the Eagles run their wide-nine defensive front. Neither of these additions should be draft choices, either. There is no time this season for learning on the job.
