The Kansas City Chiefs took advantage of the glut of available cornerbacks and added to what could be one of the NFL’s best units. They beat out the rival Oakland Raiders in the process.

The Chiefs signed former Dolphins cornerback Sean Smith. Oakland was trying to sign him as well. He was one of the best cornerbacks available, but the market has been soft.

The Chiefs added Dunta Robinson last Friday. He is a starting-quality player, but he is best served as a nickelback. The team also has standout Brandon Flowers. Adding Smith is a nice coup for Kansas City.

Oakland badly needs a cornerback, and Smith would have been the team's best. But the Chiefs won the battle.
