Jaimes/Farniok can both probably be bubble picks or priority free agents. Leaving now gives you a slight edge to make it to contract number 2 if they are to ever make it. Both still have upside that could be added by coming back, but I would be surprised if they did.
Bootle is probably an edge case on getting picked as well. He has shown overall talent/knowledge to play, but probably lacks speed/size to really make it. Could exist in hybrid corner/safety roll on 3rd down and special teams. He could be back to try and up his stock, but I would bet he takes his chances now.
Stoll's injury probably hurts his ability to get to the NFL. He would have been a fringe player who could sneak his way onto a roster, but he lost opportunities with his injuries and teams may be less excited about him. Another year could give him the stage to up his profile.
Domann is probably on the bubble as well. High motor and solid coverage skills likely finds him an opportunity to make a roster, but another year would also serve him to showcase his ability and potentially shoot up the rankings. He is likely gone though, imho.
Williams is a question. He doesn't wrap up, he constantly targets, and he is everywhere all the time. The NFL seems to forgive the first two from so many safeties, so I don't know. I don't think he will make a roster, but I think he probably tries.
Dismuke is more sound then WIlliams, but likely doesn't have the same pizazz. I think he has a better chance at making it as a special teams player, but don't know how NFL will look at his play at safety. Safeties are not highly prized, but I think he tries his hand at it.
Miller is probably not on the NFL radar anymore and, if he still wants to play, can easily come back. After his injury, he may want to be done anyway.
Miles probably doesn't have a NFL profile and could stick around another year to try again. Running backs don't last, so he should go if he wants to try, but I don't see it working out.
Honas is solid. I don't think that makes him ready for the NFL by just being a solid college linebacker. He has chances to come back and see if he can become the leader of the defense, but I am unsure if he is willing to roll the dice.
Stille and Wilson probably don't have the raw talent to make a NFL roster. They both can probably come back if they want or just give the NFL process a whirl.
Falck has seen the field quite a bit and was a consistent producer. He can stick around another year if he want to keep playing but has no future prospects more than likely.
Culp doesn't strike me as an NFL kicker. He could come back and keep kicking or just call it a day.
