Defensive Backs
This is a pretty tough position to project, both based on numbers and on an unknown on what OSU looks like. Ryan Day wanted a Cover 1/Cover 3 system, and hired Greg Mattison for that. Mattison is gone, and Kerry Coombs isn't committed to that system, and we don't know who Ryan Day will hire. So, who knows. But we endeavor.
Corners:
Sevyn Banks is the surest thing, as he started opposite the departing Shaun Wade and while he had ups and downs is a good guy to have coming back. Opposite him is a mystery. Cam Brown gets penciled in as he would have been the guy, but did suffer an Achilles injury and is a question mark until he is healthy. Marcus Williamson played the second most snaps of returning guys, but wasn't particularly great in slot coverage. Tyreke Johnson was a five star prospect but really hasn't shown that on the field and has barely played.
Young guys might get a shot. Lejond Cavanos and Ryan Watts were four star types who got some snaps as true freshmen. They also have a couple top 100 types coming in Jakailin Johnson and Jordan Hancock. While typically I wouldn't predict those kinds of guys to play right away, this position is a bit of a mess, and young guys can play. They simply don't have guys who have shown they can cover in press man, which is important if you system revolves around having guys who can play press man.
Safeties
Part of this is pretty easy. While Marcus Hooker started the season as the single high safety, he didn't look much like his brother and Josh Proctor eventually became the guy. However, I don't know that they like either guy as the main center fielder of the defense, so keep an eye on second year guy Lathan Ransom, who was getting snaps by the end of the season. Also in the mix are Ronnie Hickman and Bryson Shaw.
Finally, Kourt Williams is a guy everyone thinks will play somewhere next year, though he could move up to a Pete Werner type coverage linebacker or he could be in the mix on the back end. Once we figure out what kind of defense we will play, I suppose it will be a bit easier.
