I don't think this is a true statement. I seem to recall Miles mentioning that one of his other guys stepped up into the recruiting role after Harriman left. I have to assume we've got it covered again. Do you know for sure that we're down a guy on the road right now?
Seems to me, more I think about it, elevating the internal candidate to an interim AC makes the most sense. I'm sure we had one of the other staff members out recruiting in place of Harriman after Chris left. If you send that guy back out now, it's going to have more umph with potential recruits if you can call him an assistant coach than if you just say he's filling in for now while we're waiting to hire another assistant.
Promote the internal guy on an interim basis. Let him have the title. And see what he can do. For all we know, he's the next Craig Smith.
Eaton's on the road now, he was on the road in the gap between when Harriman left and Burno was hired. He'd be the favorite if they decide to go to the interim route, which seems likely at this point.
