Mike Jack had a breakout season & tied for the team lead in INT's, he's returning for his Senior year he'll be a starter.
Bandy has that Nickel role locked up, can also play Outside Corner too, he'll be a starter.
Dean will get his shot to get reps in the role opposite of Mike Jack, but I don't think he'll be the full time starter the whole season.
DJ Ivey especially being an EE has a great chance to be a starter, kid has great technique & footwork but needs to add weight.
My personal favorite Alphonso Jr unfortunately isn't an EE, but I think he's really talented & is a very skilled Press corner with good physicality. I expect him to hit the ground running despite not being on campus til Summer/Fall. I think he'll have a Bandy like uprising his Frosh year.
Gilbert Frierson imo is the most naturally gifted DB in the 2018 class in terms of pure ability, he's an absolute freak of nature. I think he's the quintessential Free Safety, but apparently the staff liked him at CB & the fact he's an EE gives him a great shot at it as well.
I think they'll all play, I don't how young they are, they need to play. Delaney was an experienced vet & he still struggled at times during the year, so there's no excuse to not play every one of them, I really don't think any of them should be shirted.
