I don't think anything is official yet, but here's a list of rumored UDFA signees.

Of those most likely to stick, I can pick three of them.
1. Jamiyus Pittman, UCF: DT isn't as deep as it was when Suh was here, but Pittman was UCF's best defensive lineman and produced solid numbers in his career there. I think there's a solid chance that he makes the team and earns playing time in the rotation.
2. Jalen Davis, Utah State: He graded out really well on PFF and allowed the 3rd lowest passer rating on passes targeted his way. I think I saw a few draft sites projecting him as a 4th or 5th rounder. I think he can be a backup to Bobby McCain. He's not the biggest guy but from my understanding is he's explosive and can make plays on the ball.
3. Mike McCray, Michigan: This is the least likely IMO, but I think he can be a backup SLB and a special teams contributor. Not sure his skills exactly translate to the NFL, but he's tough and produced prett ywell at Michigan.
