Another top free agent cornerback is now off the market.
Sean Smith has agreed to terms on a three-year contract with the Kansas City Chiefs, his agent, David Canter, announced Thursday on Twitter.
The final scoop on this story came from Canter, though Vontae Davis actually had it first. The Indianapolis Colts cornerback tweeted before the start of free agency's three-day negotiating period that the Chiefs were after his buddy Smith. Davis then tried to put the toothpaste back in the tube with a follow-up tweet saying his account was hacked.
Even after Davis' revelation, the Miami Dolphins, who formerly employed Smith and Davis, were still in play. But they were willing to let Smith walk even while dropping plenty of lucrative contracts on free agents from the outside.
Smith's deal is worth $18 million with $11 million in guarantees, according to a person who has reviewed the contract details. The person spoke to USA TODAY Sports on condition of anonymity because the terms weren't to be discussed publicly.
Smith is now part of a solid trio of corners - he'll team with Dunta Robinson and Brandon Flowers - suited to cover a team with multiple receiving threats. The Chiefs need not look very far to find one because the Denver Broncos just added wide receiver Wes Welker to their roster Wednesday. Welker, Demaryius Thomas and Eric Decker vs. the Kansas City cornerbacks should make for interesting matchups at least twice this upcoming season.
It's yet another big move for the Chiefs in a busy offseason that has seen the addition of Smith, Robinson, quarterback Alex Smith and the re-signing of a few other key pieces in wide receiver Dwayne Bowe, left tackle Branden Albert (who received the franchise tag) and punter Dustin Colquitt. Defensive end Mike DeVito, tight end Anthony Fasano, wide receiver Donnie Avery and backup quarterback Chase Daniel are also among the new Chiefs.
The team also holds the top pick of the 2013 draft.
The 25-year-old Smith, a former second-round pick, leaves Miami after recording two interceptions in each of the past two seasons. He'll presumably start opposite Flowers with Robinson serving as the nickelback.
