James, part of the answer would stand to what time period you are referring to. After Atlanta The AoC was given everything Sherman didn't need or want to take w/ him on the March to the Sea, the size is also misleading as many of the Regiments had been badly reduced by most of three years in the field. Add to that that the AoC was garrisoning a huge area while Shermans force was intended as a much more mobile strike force.
Almost all of Shermans Regiments on the march to the sea were seasoned veterans, including the former AoC troops... in fact it could be argued that the AoC troops that went w/ Sherman were among the best the AoC had available.
Just my two cent answer.
