Here's a closer look at the positions the Cincinnati Bengals could target at the NFL combine in Indianapolis:
Positions of need: The Bengals' defense stepped up at the end of the season, but it's clear some of their veterans have reached the age that makes it necessary for the team to look for upgrades.
Nose tackle Domata Peko, 32, is a pending free agent. Although he's been a mainstay in the Bengals' locker room, they are going to have to find a younger replacement soon.
That might be Andrew Billings, who was drafted last season but didn't play because of an injury.
