Philly does a pretty good job of replacing players it loses. The Eagles might be worse without Brown, but they did draft a first-round receiver to pair with Smith. Now, their offense was pretty ordinary even with Brown, but defense is their strength. They weren't as strong as usual last year before they got Phillips and even though they lost him, they replaced him with Greenard in the trade with Minnesota. Don't know how that will work out for them.
My contention with the Eagles is they didn't really do anything that signifies that they improved, but they probably held serve, so it's up to the rest of the division to catch them. Did we do enough to do that? We'll see.
