Let's take a look at who's staying and who's going (cue up The Clash's "Should I Stay or Should I Go?"):
First, let's examine who's definitely gone:
Emezie (WR) - Expired Eligibility
CJ Riley (WR) - Expired Eligibility
Daniel Joseph (DE) - Expired Eligibility
Dylan Parham (TE) - Expired Eligibility
Tyrone Riley (OL) - Expired Eligibility
Chris Ingram (CB) - Expired Eligiblity
Ricky Person (RB) - Declared for NFL Draft
Now let's examine who's likely gone:
Ikem Ekwonu (OL) - Likely First Round Draft Pick
Really, the biggest losses there are Emezie, Person, Joseph, Ekwonu, and Parham, but there are replacement pieces (and still more depth) waiting in the wings.
Let's talk about players to track - who has eligibility but a reason and potential for departure, and what have they said.
Isaiah Moore (LB) - "I'm back"
Cyrus Fagan (S) - Returning
Payton Wilson (LB) - undecided
Grant Gibson (C) - undecided
Bam Knight (RB) - undecided
Thayer Thomas (WR) - undecided
Devin Leary (QB) - undecided
Tanner Ingle (S) - undecided
Tyler Baker-Williams (NIC) - undecided
Derek Pitts (CB) - undecided
Cory Durden (DL) - undecided
Chris Dunn (K) - undecided
Trenton Gill (P) - undecided
Chandler Zavala (OL) - awaiting NCAA decision on waiver of eligibility
Technically there are other guys who can depart (Battle, Smith, Carter, Lesane, Pennix, Jackson, Clark, Drake Thomas, Jakeen Harris, etc), but they seem extremely unlikely. I would also assume we get the majority of the currently undecided players back (players to watch - Payton Wilson, Grant Gibson, Thayer Thomas, Bam Knight, Tanner Ingle, TBW, Devin Leary). Let me know in the comments if I missed anyone, and we can keep track as we hear any news.
