His visit with the Buffalo Bills stretched into a third day but ultimately free agent defensive end Mario Williams put pen to the paper and signed a new contract with the Bills on Thursday. ESPN's Adam Schefter and Chris Mortenson were the first to report the signing. He instantly becomes the biggest free agent signing in team history and a cornerstone of the Bills new-look 4-3 defense.

Williams most certainly signed the biggest deal for a defensive player in NFL history. Schefter reports the contract is for six years. The two-time Pro Bowler has 53 sacks in 82 career NFL games and at 27 is entering the prime of his career. Many Bills fans can now return to sleeping, eating regular meals, and seeing their families.

How does it feel, Bills fans? Buddy Nix, Ralph Wilson, and company have come through in a big way this offseason and doled out the three of the richest contracts in team history in the last nine months.

The Bills will officially announce the signing at a press conference scheduled for 1:30 this afternoon, according to Mortenson.
