The Ravens parted ways with Haloti Ngata, dealt to the Lions in the offseason. Coach John Harbaugh is confident that the center of the team's defensive line will hold up, however. 

Meeting with the media at the NFL Owners Meetings, Harbaugh said he was confident in Timmy Jernigan and Brandon Williams . "There’s no reason we can’t be a great defense and a great defensive front next year," he said, per ESPN.

Jernigan was a second-round draft pick of the Ravens last year. He had four sacks in 12 games as a rookie. 

Williams has 1.5 sacks and two forced fumbles in two years with the Ravens.
