Not sure what the displeasure is (or may be) here with this "speculation". Ken Dorsey is currently listed as "offense assistant" at Appl.St. and probably would be available if Fedora or whomever wanted him to be Canes QB coach.
Seems fair to say Diaz might be entertaining staff "thoughts" or discussions on many (MANNY?) levels, but would/probably should let whomever the new OC is pick their staff. Not saying that Dorsey wouldn't be both familiar and popular to many, and maybe will even surface in the path to "BEING BACK".
But I thought familiar face references, earlier, were regarding WR coaching possibilities.
