Casey was named second-team All-Pro last season after he recorded a career-high 10.5 sacks and 90 tackles. Casey remains one of the few bright spots on a 2-6 team and the 23rd-ranked defense in the NFL, with 42 tackles, four sacks and 15 quarterback pressures this season.
"He's a really good player," Ravens center Jeremy Zuttah said. "He's athletic, plays with good natural leverage. We've got our work cut out. I think their whole front seven is pretty good."
Before this season, the Titans signed Casey to a four-year, $36 million contract that includes $20.5 million guaranteed with a $10.6 million signing bonus.
"He's a beast," said retired former Titans All-Pro linebacker Keith Bulluck, now a member of the team's broadcast team. "He's the best player on the Titans defense. He shows up week in and week out. You look for that in a star player. He shows up. He earned that money. He sets the tone for that defense, but he can't do it alone."
