Tyronn Lue has extended an open invitation for Kevin Garnett to join his coaching staff with the Cleveland Cavaliers.

"I talked to him about it," Lue said after Cavs practice Thursday. "I know his wife is pushing for it a lot. Brandi is pushing for it, trying to get him to come and coach. He says he's not ready yet. He goes back -- 'I might do it' -- but he's back and forth. We'll see. But I'd definitely make a spot for him if he wanted to come back and coach."

Garnett retired last week after 21 seasons in the NBA.

"He's one of my best friends," Lue said of Garnett.

Lue, 39, was rooting for the 40-year-old Garnett to play a 22nd and final season in Minnesota this year.

"Didn't want to see him do it," Lue said of Garnett's retirement. "I thought he would've been the first player in NBA history to play in his teens, 20s, 30s and 40s. He just turned 40 in May. I just thought that would've been great for him."
