Making their second significant free-agent splash in less than a week, the Bills on Wednesday signed Anderson to a four-year contract potentially worth $27 million. It includes $8 million guaranteed. The defensive end is a sixth-year player who had 10 sacks with the New England Patriots last season.

"It really is a big deal for us and an exciting time," general manager Buddy Nix said. "We think this made us a lot better. This guy's about as productive as anybody around for the number of snaps he played."
Terms of the deal were first reported by ESPN, and confirmed to The Associated Press by a person familiar with the deal. The person spoke on the condition of anonymity because the team has not released the numbers.
Acquiring Anderson comes on the heels of last week's whopping move in which the Bills signed Williams to a six-year contract potentially worth $100 million, including $50 million guaranteed.
Earlier on Wednesday, the Bills also re-signed free-agent safety Bryan Scott. The nine-year versatile veteran, who can also play linebacker, returns for a sixth season in Buffalo.
Anderson's signing was the key move, coming a day after he arrived in Buffalo and had dinner with coaches and management at a downtown restaurant.
