If I had to guess (and putting a positive spin on things), Nate's current coaching staff -- his main support system -- looks like this:
Dean: looking to be a head coach, getting interviews
Monty: looking to be a head coach, getting interviews and maybe offers
Joe Prunty: former video coordinator for college and the Spurs, assisted on Spurs' Summer League Teams
Mo Lucas: been out for better part of two years with health problems
Kaleb Canales: former video coordinator, first asst. job
(Is Bayno considered a formal "assistant" on Nate's staff?)
I'd say this looks a lot like stocking up with some veteran basketball knowledge. Say what you want to about Bernie---he's basically seen and done it all in a variety of positions from asst. on a Championship team, to head coach of a playoff team, to VP/GM for a rebuilding team, to vice-president for Operations of an expansion team. If Monty and Dean leave, and Mo doesn't come back, we're left with Nate and two video coordinators/assistant coaches. Not that i have anything against video coordinators, but I'm pretty sure there's a reason that most staffs have a few assistants--to widen the pool of shared knowledge.
