Looks like it will be Richard, Flores, or Rizzi. Unless a mystery candidate pops up. Miami will offer Richard as soon as this weekend if Dallas loses to the Rams. The dots seem to connect to him being the #1 choice. If for some reason he says no then Miami will move on to Flores. New England will probably win this weekend so if that happens Miami can't interview him again until after the AFC Championship game. So Miami will have to be patient. If for some reason Flores says no then Rizzi will be their 3rd option. We know he will accept.
Richard or Flores will bring an experienced OC and their DC will probably be a position coach that they will elevate to DC. They will want their stamp on the defense so most likely they wouldn't bring in a Bowles, Williams, type experieced coordinator. Rizzi will try to bring the most experienced coordinators he can as he will not have to be overseer of either side of the ball but will be more of a CEO and allow his coordinators to do their thing.
I have no sources just my random thoughts after reading all that's out there.
