Houston formally made the move on Monday in advance of August 30th, when his $916K salary would have become guaranteed for next season. Stein notes (via Twitter) that the Heat have expressed interest in Williams in the past and are likely to consider him again as they are in the market for bigs.
Williams, 25, fell to the Nets in the 2007 draft and was tabbed with the 17th overall selection. The shot blocking specialist was considered to be a lottery-level talent but had a number of red flags surrounding him which led to his dismissal from the Boston College basketball program. Williams has since played in China, Puerto Rico, Israel, and the D-League before having cups of coffee with the Mavericks and Celtics.
