The grad transfer market has become one of the most fertile late season avenues to land players...only if you have an obvious depth issue and a position and immediate playing time is clear. With Starks, Mitchell, Chandler, Wheeler, and possibly even Gilder, I think the opportunity to get another quality guard out of the grad transfer market will be tough. Plus, Harris is a freshman and the value is getting him in the pipeline for a long period of time. One of the problems Kennedy had was he started relying heavily on grad transfers and JUCO's and that compromises your high school recruiting to some extent. It's kinda like recruiting one-and-dones. Once you start, it's hard to stop that cycle of short-term players coming through the program for many reasons.
Teams have been recruiting the JUCO market for months, so that will be a tough place to pick up talent for the new coach, unless he had a few on the string from his previous job. Most of the high school talent left unsigned are the elite 5-stars picking from UK, Kansas, Duke, and UNC. There may be a few late bloomers out there, but not much will be left for a new coach.
The best scenario is the new coach meeting with Harris and putting his fears to bed...and I assume that will happen.
