Three weeks into the preseason the Nets still are waiting to hold their first practice in which all 15 players are healthy and involved. In fact it took until Tuesday for the Nets to have their first portion of any practice involving the full participation of their star-studded starting five in full-contact drills.

For someone as notoriously particular as Kevin Garnett — a player who already has openly complained about sitting out of preseason games in this his 19th NBA season — you would think that would leave him frustrated with the progress the Nets have made in bringing their many new pieces together.

But Garnett says that’s not the case at all thanks to the fact from his perspective all 15 players on the roster are pulling in the same direction.

“Cohesiveness is something difficult” Garnett said following Tuesday’s practice. “Chemistry is even more difficult. But what kills all that the difficult part is when everybody is willing and everybody is open and everybody wants to be cohesive and join. The chemistry that has been joined here is guys want to get to know each other and understand each other’s strengths and weaknesses.”

The player most conspicuously absent has been Deron Williams who participated in his first 5-on-5 contact portion of practice of the season on Tuesday when he spent 15-20 minutes on the floor with the other four starters. Williams has spoken at times about the frustration he has felt in not being part of the team — instead as he put it Tuesday he has felt like “part of the cheerleading squad” at times.

But even though the team’s floor general hasn’t been on the floor Garnett said Williams still has had a big impact on the new-look Nets.

“Although Deron hasn’t been on the court with us in practice throughout camp doesn’t mean he hasn’t been present” Garnett said. “It doesn’t mean he didn’t initiate the workouts [in Los Angeles this summer] … [training camp at] Duke the dinners the game rooms up late night talking …. on the plane card games in the back talking.

“Whatever it is we’re willing to do that we’re willing to come together and join that. When you see teams that are not cohesive it’s because one everybody is stagnant everybody is closed they’re not open to one another. Here that’s not the case. We all understand the one goal we have in common and we’re trying to reach that goal.”

If anyone wondered at any point what the goal actually was they’d have to answer to Garnett himself. His addition has given the Nets the kind of vocal presence they didn’t really have a year ago something Williams himself admitted Tuesday.

“Kevin he’s so vocal and I’m not used to being vocal that way” Williams said. “For him coming in here he’s the vocal guy so I just go out there and play. I definitely talk to guys but he’s a motivator in your face high-intensity every play.”

That was something the Nets lacked at times a year ago thanks to the more low-key personalities of Williams Joe Johnson and Brook Lopez.

“I think [his presence helps] because I think a lot of us are more quiet” Williams said. “Joe is definitely quiet Brook’s quiet. I was the most vocal last year so that definitely hurts a little bit.”
