"Many league insiders" believe current Spurs assistant Mike Budenholzer will wind up with the Hawks head coaching job.
Budenholzer's name is getting to be scorching hot in coaching circles and we would be shocked if he's not a head coach next season. He's been very important on Gregg Popovich's bench, but he deserves a shot at running his own team.

Larry Drew would be interested in the now-vacant Clippers head coach position, according to Hawks beat writer Chris Vivlamore.
Drew is still technically coach of the Hawks but is operating under the impression that he is a free agent. He's already interviewed for the Bucks job and could interview elsewhere as the job market develops. The Clippers job became open when owner Donald Sterling declined to offer Vinny Del Negro a new contract. It remains to be seen if they'll have interest in Drew or whether this is simply Drew's way to trying to flag down every potential interview before all the head coach jobs are taken.

Hawks coach Larry Drew says he will interview for the Bucks' head-coaching vacancy on Monday.
It might seem strange for a coach under contract to be interviewing elsewhere, but Drew told Hawks beat writer Chris Vivlamore that he and GM Danny Ferry agreed to allow Drew to interview elsewhere. Drew said he won't rule out returning to coach the Hawks but said he's "moved on from the situation" in Atlanta. Meanwhile, Ferry has already interviewed at least three candidates to replace Drew and there was a report the number is actually bigger than that. It seems only a matter of time until Drew is no longer officially employed by Atlanta.
