Well, Bubba Edwards as the OC. No word on DC unless Ronnie takes it himself. I think he has experience as a DC. So the "top 3" positions could already be set. Edwards will be the QB coach...or at least he was at his previous stops.
So, not sure of the LB, RB, DL, OL, etc. I thought there was some carry over from a few of last year's staff. I think Breeding returns as RB coach...not sure if he coaches defense. Also, I think Ronnie has OL experience...so maybe he works with that position on offense. That's a lot of work for one man, though.
