The Raiders get the ball rolling in the second day of free agency. Veteran CB Sean Smith, most recently a Kansas City Chief, has signed with the AFC West rival Raiders, on a four-year deal. Smith will reportedly receive $40 million, with half of that guaranteed. Smith has been one of the more solid corners in the NFL since entering the league as a second round draft pick of the Miami Dolphins in 2009. After playing out his rookie contract in Miami, he was one of the more highly sought-after corners in free agency in 2013, opting to sign with the Chiefs. There, he was a core part of a secondary that contributed to a top-ten passing defense in both of the past few seasons, and he was elected to ProFootballFocus’s All-Pro team in 2014. His 2015 campaign did start on the sidelines as he served a three-game suspension for a DUI, but prior to that, he had missed just one game in his career, speaking to his durability. The Raiders hope that Smith will have an immediate effect on what was the seventh-worst passing defense in the league last season. By adding both Smith and pass rusher Bruce Irvin, it’s clear that Oakland are making improving their passing D a priority. To do so, they’ve given Smith the 11th-biggest contract for any corner in the NFL on a per-year basis, with his salary falling between the Cowboys’ Brandon Carr and the Packers’ Sam Shields. If Smith can repay the Raiders’ confidence in him with the sort of performances we’ve seen out of the Utah product the past few seasons, then the Raiders will have continued their transition from the league’s laughing stock to a team seriously building a long-term contender.
