"Mario Williams is certainly a force," Ravens offensive coordinator Jim Caldwell said. "He can really turn it on. I had the pleasure of playing against him twice a year when he came in the league when he was in Houston. I saw what he can do, what he’s capable of.
"He’s a guy that has speed and power. He can get up the field and create some problems on the edge, but he also has enough power to really knock you out of the way and get to the quarterback."
Despite injuries last season, Williams recorded 10 1/2 sacks last season in his first season with the Bills after signing a $100 million contract to leave the Texans. As the Bills' right defensive end, Williams will primarily be matched opposite left tackle Bryant McKinnie on Sunday.
"We studied him on film and watched some of the moves he likes to do," McKinnie said. "I've played against him a few times and he's pretty tall with long arms. He's a good player."
McKinnie said he was eager to move on from the party bus incident early Monday morning where Pro Bowl kick returner Jacoby Jones was hit in the head with a bottle while celebrating McKinnie's 34th birthday.
"Yeah, I'm ready to make sure that the game is my main focus," McKinnie said.
