Buffalo Bills linebacker Manny Lawson was blissfully unaware of his new team’s shortcomings.

“That is new knowledge to me,” he said Wednesday during his introductory news conference, when asked whether he had any preconceptions about signing with a team that’s failed to make the playoffs for 13 straight years. “I guess it’s good to know. I look at myself as: I’m coming here to change things.”

The Bills showed they believe Lawson can be a part of the franchise’s revival by dipping into the free-agent pool for the first time in 2013 and signing him to a four-year contract worth up to $12 million.

“This team really wanted me here,” said Lawson, who arrived in Buffalo on Tuesday night, the opening of free agency, “and that was just enough for me to come here.”

Lawson, 28, is a versatile defender who has experience the last two seasons in the Cincinnati Bengals’ base 4-3 scheme. But at 6-foot-5 and 240 pounds, he’s ideally suited to be a 3-4 strong-side linebacker, and he wanted to return to that role, which he played for San Francisco — the team that picked him 22nd overall in the 2006 NFL draft — at the start of his career.

His signing is an indication the Bills will line him up in that role in the new scheme installed by defensive coordinator Mike Pettine.
