Last week, Celtics forward Kevin Garnett said he no longer wanted to discuss his surgically-repaired knee.

On Monday, he acknowledged that it has taken him time to return to form. He is starting to attack the glass with authority and show flashes of his former athleticism.

"Physically I feel really, really good," he said. "But you all have no idea of the [stuff] I go through to come in here and be Grade B, Grade A. So I'm a work in progress. I don't even think twice about my leg. There's nothing about this game I second-guess. As a basketball player you have to react. When I am reacting and [stuff] flows, I'm a better player like that. I'm trying to find timing in what [coach] Doc [Rivers] wants and making it come together."

Garnett added that he's almost solely focused on defense because Boston has so many offensive options. He hit two jumpers within 94 seconds to help seal a win on Sunday.

"I wasn't even going to it but Paul [Pierce] was on my [butt] on the bench about being aggressive, take the shot, take the damn shot," Garnett said. "Here I'm just a piece that fits in the puzzle. And I'm thinking more defensively since I have been in here, since I stepped foot in here, put the jersey on. I am just more of a defensive player and I like that. Coming in I want to make sure defensively I am sound. When I am not forcing the issue and not thinking everything else just flows. So I think that's all you see."
