I don't have info that conflicts with Lloyd, but I would think the person who has the most chance to be around next year is Posey, since they just hired him for Summer League. You can see other coaches, like Handy, involved in recent Cavs footage like the Wiggins workout. Clearly Boylan, Brielmaier, Handy, and Potapenko are valued since they're going to Summer League, but the Cavs may not have been spending a lot of time sorting out their assistant coaches the past week or two. Is Kokoskov gone with Lue on board?
I would be a little surprised if Blatt doesn't make one hire who is "his" guy. Seems like he really likes Lue, and maybe that is enough. But to come in to a brand new job and you have 4 coaches from the previous regime and a guy who also applied for the job seems like a little odd from the outside.
I will say that I like an assistant staff with 2 former nba players, 1 old-coaching hand, 2 development guys that have been around the team, and whatever it is that Breilmaier does other than halftime interviews (kidding, sounds like he deals with video stuff among other things).
