Outgoing:
Chase Smith - super senior, presumably gone (heard the thing about another medical shirt)
Adarius Hayes - legal issues, presumably gone
Wes Bissainthe - Senior, played 4 years, would have to somehow apply to return
Jay Alderman - RS Senior, presumably gone
Mo Toure - Grad Student, presumably gone
Possibly returning:
Malik Bryant - has eligibility, but more of a standup End, it seems, has struggled in space
Popo Aguirre - will presumably be part of the rotation
Cam Pruitt - hybrid player, more of a Safety this season
Kellen Wiley - would have loved to see more snaps, will presumably be part of next year's rotation
Kamal Bonner - don't know much about him other than he stood completely still on a TD play
Ezekiel Marcelin - haven't seen him enough; unproven and untested
Bobby Washington* - didn't originally list him because had heard his injury was serious and no idea what that means going forward
Incoming:
Jordan Campbell - highly rated, but may fall into the Malik Bryant stand up Edge player role or even a clearcut DE
Justin Edwards - needs weight
Karsten Busch - people like him, I don't know much about him; the limited stuff I did see didn't look as fluid (sideline to sideline) as I'd hoped, but maybe more of an inside thumper player; would need to see more.
Now, this isn't how I make a living, but if I'm looking at that situation, I'm requesting a bigger budget asap. Next year's defense may be above average to elite at DL and DB - with a couple additions in both. I hope we don't find ourselves with a "the LB position kept us from what we could be" situation.
*I'm sure I missed some stuff. Here for the discussion.
