The Cleveland Cavaliers have received permission from the Denver Nuggets to interview Wes Unseld Jr. for their vacant head coaching position. 

Unseld, who is Michael Malone's lead assistant, is considered the brains behind the Nuggets' top-10 defense.

J.B. Bickerstaff, who interviewed for the position on Tuesday, was optimistic about the Cavs' future.

“I know the quality of people that they have there. I’ll let my agent handle all the conversations between the teams and that type of stuff, but I think they have a group of people in the front office that are trying to do things the right way," said Bickerstaff.
