Leo: Vereen
DT: Owen Williams
DT: Saulsberry
DE: Jordan Williams
The starting 4 on the DL doesn't mean a whole lot because we'll rotate a lot of guys and many more than 4 will get significant snaps. Carr, O'brien, Lewis, Miller, Mixon, Henderson, Hendrix, and Barnett all have a shot at seeing a lot of snaps. Vickers, Malik Brown, and Mosely are deal horses to crack the rotation.
OLB: Maggit
MLB: AJ
OLB: JRM
I think Weatherd's skillset is similar to Maggit's and he'll back him up for the most part. Both could be used as speed rushers on 3rd down. JRM seems like a pro type WLB who should be athletic enough to play 3 downs. Bates is a dark horse to crack the rotation at that spot because of his athleticism and instincts. Justin King is a wildcard here because we haven't seen him at LB. I have a feeling the coaches redshirted him for a reason and we may see a lot of him this season (especially if Maggit and/or Weatherd end up playing closer to the line of scrimmage as some are speculating could happen).
CB: Coleman
NB: Payne
S: Randolph
S: McNeil
CB: Sutton
IMO this is the hardest position group to project. I put Payne at NB over Gaulden because he'll have spring practice as an advantage. One of Kelly, Gaulden, or McDowell could snag the safety spot from McNeil, but I'm not sure it will happen since none are EEs. I'd consider Riyadh Jones and Malik Foreman dark horses to steal Coleman's spot or the NB spot. Evan Berry is a wildcard and if they stick him on defense he's athletic enough to have a Sutton-like impact.
TL;DR: There are a lot of variables at each position group.
