I know GH has said there will not be an exhaustive search for a head coach, but realistically, there's probably only about 4 options who can join part-way through the season. There's probably only 3 more you would realistically add to that list once if they'll wait til the off-season (I'd count Tony Smith/McGuire in that camp). So I can't imagine we'll be waiting long a decision.
Given the radio silence out of HQ, I imagine they're already in advanced talks to get a coach in as soon as possible.
