“He’s not coming back. For me he’s not coming back because it’s not helping,” said Manu. “We fell for it a week ago. Again. I guess you guys [the press] made us fall for it.”
“We got to think that he’s not coming back,” said Manu. “We are who we are. We’ve got to fight without him.”
Head Coach Gregg Popovich stated the same thing after the recent All-Star break, saying he doesn't expect Leonard to come back at all and if he did, he'd be surprised.
