Mark Madsen was recently hired as an assistant coach for the Utah Flash of the NBDL. He talked about it here.
I have to say that reading this news makes me very happy. Mad Dog seems like such a great person so it's nice that he's getting an opportunity to coach - which he apparently likes very much.
So cheers Mad Dog! Good luck with the Utah Flash. The only advice I can give you is to stick to teaching them basketball and not dance moves.
