We signed Dennis Thames, Nickoe Whitley, Johnathon Banks, and Cameron Lawerance as DBs last year. I think Billy Hamilton was also considered a DB or WR, but was drafted to play baseball.
I think Thames is now considered a WR, Banks has played at safety, Lawerance play special teams & will probably be a safety or LB if he adds much size, and I don't think Whitley is expected to play this year - he was injured his SR season (knee maybe??).
Edit: forgot Langston - he played at CB at least once last night.
