It should be Gino Guidugli.
As a place holder.
To get an elite OC, you have to be willing to let that OC have some input on his staff. Heacock turned down the DC job over not being able to pick his own position coaches.
Give Guidugli one season to prove himself. It either works well, or you shake up the entire offensive coaching staff by bringing in a proven OC who is able to pick his own staff. Maybe he retains a couple of coaches like Deland McCullough and Mike Brown, though I expect McCullough will be moving on after next season with a promotion.
