Ainge said about the young point guard during an interview appearance on The Big Show
"I'm not so sure I've ever seen a point guard dominate an NBA game to that extent, ever, defensively," Ainge said. "That was impressive."
On the stat sheet, Bradley had 6 points, 4 defensive rebounds, 3 steals and a block during the Celtics' 87-56 win.
Ainge was not as glowing when it came to Bradley's offense, but noted that his defensive hustle could impact Bradley's production.
"Time will tell. Doc [Rivers] has told him get out there on the court with your defense and let your offense evolve. He's been a terrific offensive player wherever he's been. He's never been a true point guard. He's always played the two-guard position, so that's a transition for him. But I've seen progress just in the few games he's played. He's still not comfortable and confident. On the other side, I'm not so sure anybody can shoot with precision when you put forth the effort and energy that you do on defense. I think that's one of the hardest thing in basketball is to reach guys to play defense like a linebacker and offense like a quarterback. That's very challenging."
