This is my ranking of the OPs list in order:
Jermaine Johnson, EDGE, Florida State
Tyler Linderbaum, OC/OG, Iowa
Andrew Booth Jr, CB, Clemson
Zion Johnson, OG, Boston College
Nakobe Dean, LB, Georgia
Jordan Davis, NT, Georgia
Drake London, WR, USC
Jameson Williams, WR, Alabama
Trey McBride, TE, Colorado State
Chris Olave, WR, Ohio State
Demarvin Leal, DL, Texas A&M
Devin Lloyd, EDGE, Utah
David Ojabo, EDGE, Michigan
Travon Walker, DL, Georgia
Kaiir Elam, CB, Florida
Just a note on Elam. If you watch his games he is extremely soft. Shies away from tackling and gets blocked up easily by WRs and does not shed blocks well at all. All of which are the total opposite of what we look for in our DBs.
