Nobody has much idea on the DC that would come with Moore. Some are speculating that it could be Brandon Staley since Moore worked under him with the Chargers and Staley is available. Or will be since he is not expected to go back to SF on Saleh's staff.
As far as the OC, most seem to think it would be Doug Nussmeier who has followed Moore to every place he goes.
As far as scouting, the scouts just gather info on all the players and then later before the draft the HC, Irleand, Loomis, and Mueller will stack the boards based on the new schemes and what the HC likes. At this point, all of the scouting is more or less done anyway. But, according to Underhill, we have most of the front office at the Senior Bowl at this point.
