One Detroit Lions free agent who hasn't received a ton of attention is defensive tackle Corey Williams. It's not clear if the Lions have any interest in bringing him back, but he has received some interest on the open market. Actually, he visited the Oakland Raiders on Thursday, although it didn't result in a deal.

Last season, Williams only appeared in seven games because of injuries. He lost his starting spot to Nick Fairley as a result, but it's not like Williams' play declined all that much. He still had 2.0 sacks and 1 forced fumble in his limited time on the field, and he still appeared to be playing at a starting-caliber level.
Williams will be 33 by the start of next season, so perhaps the Lions want to get a bit younger at defensive tackle. Given their lack of depth at the position right now, I wouldn't be opposed to a one-year deal for Williams, but he doesn't seem to be a priority for the Lions right now.
