Sixers general manager Ed Stefanski interviewed each former NBA player on Monday in Phoenix. Stefanski says both assistants are valuable assets on their respective benches.
The 76ers also have talked to Avery Johnson and Doug Collins. They fired Eddie Jordan last month after the team went 27-55 in his lone season.
A person familiar with the meeting told The Associated Press that Williams headed to New Orleans after the meeting to interview for the Hornets' vacant head coaching position.
The interview is set for Tuesday.
