Kansas City Chiefs: It’s difficult to find anyone who would argue that this wasn’t a winning offseason. In fact, the Chiefs might be among the biggest winners in free agency in the entire league. The Chiefs were aggressive and addressed every big need. First, they traded for quarterback Alex Smith, answering their most glaring hole with the best available player at the position. Then, they kept three key free agents in receiver Dwayne Bowe, punter Dustin Colquitt and left tackle Branden Albert. And after that, the Chiefs jumped aggressively into free agency. The additions of Dunta Robinson and Sean Smith could give Kansas City the best group of cornerbacks in the NFL. The Chiefs added in several other areas, including field-stretching receiver Donnie Avery and run-stuffing defensive lineman Mike DeVito. The new brass is determined to move on from the 2-14 disaster that was 2012.
