How many players actually have used up all eligibility after this season?

I'm glad to hear Amos and Story are coming back. Story hasn't impressed necessarily but I think he has ability. Amos has held up well when push into duty. I'm hoping that Malachi Moore decides to come back. I think it is more likely than some others because he's an in-state kid. Downs, Story, and Moore as safety/nickel types and Amos at corner means we'd only have to find a starting corner and depth.
