Bills' defensive line is looking scary

The Buffalo Bills' already stout defensive line just got even better.

Buffalo signed former New England Patriots defensive end Mark Anderson to a four-year contract Wednesday. Anderson joins fellow defensive end Mario Williams and defensive tackles Kyle Williams and Marcell Dareus on Buffalo's defensive line.

The Bills had trouble getting to the quarterback last season and made it a point to put their resources toward fixing the issue. Anderson recorded 10 sacks for the Patriots last season. Williams has 59 career sacks and is one of the NFL's best pass-rushers. Consider the problem solved.

Buffalo's defensive line is looking downright scary. The group will be very tough to move in the middle and pass protect against on the edges.

The Anderson signing also hurts the reigning AFC East champion Patriots. New England lost last season's team leader in sacks to a division rival. The Patriots are looking to add pass-rushers, not lose them.

For the first time in a long time, Buffalo is spending big money and making moves in free agency. Bills general manager Buddy Nix said the team will be major players this offseason, and Nix continues to prove it.
