Best guesses given current intel:
OC - Garrick McGee (new info calls him "clear top target")
RB - Scheelhaase? I've also heard he was offered a non-coaching role with the team
WR - Andrew Hayes-Stoker
OL - Tim Holt
DC/LB - Hardy Nickerson
DL - Mike Phair
DB - ? I know that Miles Smith is going for his Master's; is Mikal still in play? If not, Gill Byrd has been with Lovie at pretty much every stop.
ST/Assoc HC - Dave Toub (not sure he'd be interested)
That would be a pretty insane coaching staff. If one more big name signed on, it would be over the top - clearly elite nationwide. My only concern is McGee's mixed track record, but he's clearly well regarded in the coaching community.
