NFL free agency: Dan Williams reportedly to sign with Oakland Raiders

The Arizona Cardinals' 2010 first round pick has reportedly left the team. According to ESPN's Michael Wright, nose tackle Dan Williams is going to sign a contract with the Oakland Raiders.

Williams played five seasons with Arizona and was a staple in their base defense and big part of their success against the run. He played 70 games, starting 40, collecting 113 tackles, two sacks and an interception for a touchdown.

While he was an important part of the defense, he never played more than about 40 percent of the team's snaps, as he really only played in base and jumbo packages. He was fantastic against the run, but wasn't considered much of a threat rushing the passer.

He was Pro Football Focus' eighth best defensive tackle/nose tackle against the run, using their grading system.

Arizona did not make much effort to retain Williams and it was rumored he was going to command more than $3.5 million per year. According to Kent Somers, Williams will get an average of more than $6 million per year with $15 million guaranteed.

Arizona has re-signed nose tackle Alameda Ta'amu and is reported going to sign veteran Corey Peters, who can play nose tackle.
