I heard Dom Waters on 95.5 yesterday and according to him all of the current key players are sticking around. Geving said in his press conference said that Jacobsen and Harriel were staying on as well as and couldn't comment on Jones and Lozeau, but pretty much said they're a done deal too.
With respect to the assistant coaches Waters said he thought that all of the current assistants would be staying (Allen, Raiford, and Harper) and that they would just be hiring one more assistant essentially to take Geving's spot. However in the press conference Geving didn't name any assistants, but said it would be settled in the next week or so. I wouldn't be surprised if Bone ends up taking one of the assistants with him as he has an entire coaching staff to fill out.
All in all I think this is the best case scenario for PSU basketball considering that Bone left. If all this holds to be true we shouldn't miss a beat and should have the most talent of any team in the Big Sky once again.
