Offensive Coordinator

Before Dinwiddie left for Calgary was he designated to remain as the Co-OC for the Als?
Has there been any discussion on replacing him or have the Als officially declared Calvillo as the offensive coordinator and just leave the Dinwiddie position unfilled?

Couple of "wonder if" type reports that I recall, but no serious talk.
I think it would be a good idea; give AC a full season or two as QB coach and ass't OC.
