Looks like Dwane is the leading candidate. Well from this article, it looks like he is a carbon copy of Woody. Please read the article and put in Woody's name anywhere you see Dwane's name and you will get the same criticism we "so called experts" here in ATL have of Woody.

Oh and just for fun, he was 20 -20 and even though his replacement was 12-30, the writer still did not have anything good to say about Dwane.Even 3 years after he left, the writer still does not have anything nice to say about Dwane despite the fact that he has been their best coach in terms of record in quite a while.

BUYER BEWARE: If you are looking for a coach that will play basketball that is pleasing to the eye, you have got the wrong man and if you are looking for a coach that is more concerned with winning than anything else, then we just mighty have a Woody clone.

See my favourite quote below. 

(S4G): Which were Casey’s strengths as a coach, and what was he missing?

(CW): I honestly cannot remember any “strengths” besides the fact that he was a nice guy. Also, I think he did a decent job getting our players to play defense during his 20-20 second season, although the stats might say otherwise (I didn’t check). 

He was missing everything. Namely: experience, presentation, advanced game knowledge/strategy, good assistants, and good players.
