The new Net said last week that it was time for Brooklyn to take over New York City from the rival Knicks.
Asked how the Nets could surpass the Knicks, Kidd replied, "Well, we gotta win a championship."
"Paul has a lot of confidence. And I think that's something that he can share with the guys on the team," Kidd added. "Some like to say it to the public, some like to just go out and play. So there's nothing wrong with having that confidence, and we all support him."
Pierce told Complex Magazine that he hates the Knicks "with a passion."
"Let's start it up right now," Pierce said. "Let's start the beef. It's no secret that me and New York got history. It's no secret. This is no secret. It's already known."
Kidd's new title: Coach Kidd, who was still an NBA player in May, is settling into his new role.
"I'm excited. We just had our coaches retreat so, I would say I'm comfortable with being called Coach now, but I think there's still a lot of work to be done," Kidd said. "There's still a lot for me to learn."
Brook getting better: Kidd addressed how center Brook Lopez (foot surgery) is progressing.
"He's got his boot off and he's ready to go in the sense of probably starting to work out a little bit," Kidd said. "We're not looking for any setbacks, but he's been cleared and he's out of the boot and now the next step is to slowly get back into shape and get ready for camp."
Roster is deep: Asked about the additions of Andrei Kirilenko and Alan Anderson, Kidd said, "It makes us deep. ... AK can start if we have guys that are out. It just gives us depth, shooting, defense, being unselfish, and the biggest thing is that all the guys we have want to win. And that's the biggest part of having some success is that everybody wants to win."
Kidd said he'd like to establish a 10- or 11-man rotation early in the season. His goal is to utilize his team's depth in order to keep his veteran players fresh for the playoffs.
Bring on the Heat: Kidd on the team's Nov. 1 home opener against the defending champion Heat: "I think it's a great opener for our fans and also for us to see where we are. It's early. I've always thought when you get to March or April you won't remember who you started the season with, but it's a good way to kick off the season for us."
