Considering Hunter was essentially the head of scouting, as well as other AGM duties, I went with Chuck Fletcher. It would be a step down for him, since he was the GM in Minny, but I think he's the best man for the job. Plus he could handle more than just scouting, as Hunter did, so there's less of a gap left over.
If we were to pick just one of those candidates to hite as an assistant GM, I would pick Ron Francis. However, I don't know too much about his scouting prowess to say he could fill Hunter's shoes. Most of the best scouts are people whose names we never hear. For Francis I like that history would be repeating itself a bit, leaving Carolina for a shot at a Cup in Toronto.
