According to Adrian Wojnarowski of ESPN, the team has received permission to interview both Nate Tibbetts and David Vanterpool. Neither has been a head coach in the NBA before but bring a significant amount of experience on the sidelines as assistants.
Vanterpool has spent seven seasons with the Trail Blazers and two years with the Oklahoma City Thunder, as well as the NBA's Basketball Without Borders. The 46-year-old also spent one year in the NBA as a player with the Washington Wizards.
Tibbetts has the advantage of spending two previous years with the Cavaliers from 2011 to 2013 before moving on to work in Portland.
He also has head coaching experience in the G League as well as at the Pan American Games.
On the other hand, Bickerstaff has more experience as a head coach after spending parts of three seasons in charge of the Grizzlies and Houston Rockets. He was fired earlier this month after going 33-49 with Memphis, but has been on NBA benches since 2004 and apparently still fits Cleveland's profile.
General manager Koby Altman discussed what he is searching for in the next coach:
While there were reports the team was interested in former Louisville coach Rick Pitino, the Cavaliers denied the rumors, per Chris Fedor of Cleveland.com.
After moving on from interim coach Larry Drew, the organization could use someone who can handle a young roster during the upcoming rebuild.
