Oakland Raiders fans were this writer's worst critics when previewing free agency the past two-plus months. They just couldn't fathom how we couldn't see them getting a whole lot better with so much salary-cap space.

After the first week, they aren't going to be any happier. Their team got older. And it got embarrassed.

The NFL free-agent period has proven the rich merely get richer. We present you an eight-part slideshow of the top winners and losers the first week of free agency, with a heavy lean toward the teams that made the quick-strike additions—both in quality and quantity.
