WALTHAM — If there’s one player on the Celtics  to trust when it comes to talking leadership and intensity on defense it’s Kevin Garnett . And when he says Avery Bradley  is the most important player in the team’s complex defensive scheme, you can’t help but listen up.
“He is everything to our defense,” Garnett said of Bradley on Monday before practice. “I think he’s the anchor. He’s the true inspiration of what it is. He gets up on the ball, 95, 90 percent of the time. Look at any other guard in the league; no one in the league is playing defense like he is. He’s just tenacious. He’s the silent leader and it’s by example.”
How big has Bradley been?
Last Friday, going up against Stephen Curry, the Celtics trusted him to go man-to-man and disrupt one of the most explosive players in the league. When he picked up his fifth foul with eight minutes left in the third quarter, the Celtics had to switch to a zone. With Bradley back since early January, the Celtics have gone from 25th in the league in defense to ninth, allowing just 95.9 points per game. They have allowed 100 points just six times since. Three of those six went overtime, including the triple-overtime game against Denver on Feb. 10 and another game he missed altogether.
Our Ben Rohrbach made the case for Bradley landing on the NBA All-Defensive team , which at this point seems like a no-brainer.
Reminded that Bradley has occasionally calmed coach Doc Rivers  down this season, Garnett said that it’s been Rivers who has been the steadying force in Bradley development this season, especially as a court leader with Rajon Rondo  out injured.
“I think it’s the other way around, although he isn’t really loud, he’s very vibrant,” Garnett said. “I don’t think he’s 100 percent, which is scary. I think he’s still working through some things with his past injuries but he’s playing hard and he’s giving us everything he has when he’s on the floor.”
Rivers isn’t asking Bradley to be vocal on the floor, since his play is speaking volumes.
“I think his play speaks for it,” Rivers said. “He has to call plays out and stuff like that. I think he’s verbal, defensively, in what we do. But that’s not anything I’m looking for right now from him. I just want him to keep playing, and playing hard. He plays so hard, he probably can’t speak half the time because he’s exhausted. I just like what he’s doing.”
Rivers said Bradley has been impressive this season after having a pair of shoulder surgeries in the offseason.
“I think he’s 100 percent, leg-wise,” Rivers said. “He’s been 100 percent. I guess if there’s any good thing about having a shoulder [injury], you can still use your legs, conditioning-wise. You can do all the running. As far as his shoulders, I can’t answer that. I don’t know. I would say he would not be 100 percent until next year with that.
With any surgery, especially when you have two, [takes time]. One of the officials in the last game walked up to me and asked, ‘Avery have both shoulders done?’ I said, yeah. He said, ‘Man, I had one done, I was out six months and I still feel bad.’ And I said, ‘That’s why you’re an official.’ I did get three bad calls after that.”
