The one they had to fix is still broken. The Chargers left interior defensive lineman untouched, and that omission hangs over an otherwise reasonable haul. The bottom line is a respectable B-.
Sawyer has a lot of ground to make up just to look fairly priced. Job largely done: edge rusher settled and 1 of 8 of the wish list covered. Building through the lines is a philosophy, and they stuck to it.
In short, they left a little better than they arrived, which is the whole idea.
