Here is a quick little review of players that I believe could be decent depth options to consider. These guys are projects and the goal is not to find diamond in the rough, but a piece of silver would do well.
Martez Ivey - OL - He profiles more as a guard in the NFL, provides some swing tackle ability to be a multifaceted offensive lineman.Good size, power, and decent feet with the ability to pull.
Jordan McCray C/G - He was a center for Tampa, did a good job at the point of attack, showed the ability to chip and get to the second level.
Cavon Walker - DT Maryland linebacker that lacks the ideal size, not going to wow on any metric, but improved hands and smaller frame gets under the guard an center. He showed a constant motor and decent first step. He could be a nice look at interior depth.
Anthony Johnson - DE/OLB Bounced around a lot and slightly long in the tooth. His game tape is better than the metrics and might be a product of the coaching he has received against this level of competition. He does offer size, defensive IQ, likely better in the run game, but decent bull rush to think he could be a backup DE, maybe special team player.
Dexter McCoil - Hybrid He was not good enough to be a true safety, but too small to be a linebacker. He was playing linebacker for St. Louis and was sideline to sideline, holding his own and willing to stick for interior run plays. I believe this type of player is where the NFL is moving towards in third down situations. He is 28, limited, but could be a special team player and poor man peanut.
