Humphries was sent from Washington to Phoenix in a trade at the deadline that brought Markieff Morris to the Wizards. Since the deal, Humphries has played four games for the Suns, averaging 7.3 points and 8.0 rebounds. He is making $4.6MM this season and in 2016/17, so it’s uncertain how much money he would have to give up in the buyout.
The Hawks have a roster spot open, so no corresponding move would be needed to sign Humphries. If the deal happens, Atlanta would be his seventh team in a 12-year NBA career.
