Stephen Jackson walked into the Bradley Center media room with this greeting: "What's up, everybody?"

Yes, you can say the Bucks' new wing player has a presence when he walks in a room. And the 33-year-old Jackson also believes he can make a difference on and off the court for a Bucks team anxious to return to winning ways after a disapppointing 2010-'11 season.

Jackson gave no apologies for the way he plays or his sometimes volatile nature with referees. And he said he was more than ready to play for the Bucks, despite early reports to the contrary.

"First of all, I'm definitely happy to be here," Jackson said. "If you have any questions and you want to know how I feel, you can ask me and I'll give you the answer.

"I'm excited. I want to win. This is a great place to win. The coaching staff I'm definitely familiar with and I have a lot of respect for. There are guys on this team I respect and I'm friends with."

Jackson later said he did not want to be part of a rebuilding team in Charlotte and was much more eager to play for a Bucks team making a serious bid to return to the playoffs. And he said he understood the thinking of the Bobcats in trading him as they moved up in the draft to grab 18-year-old center Bismack Biyombo with the seventh overall pick, as part of the three-team trade with Milwaukee and Sacramento.

Jackson said he will take a leadership role with the Bucks from the start.

"I have to be, because it's not something that he (coach Scott Skiles) is going to have to ask me to do," Jackson said. "It comes natural. Being a leader is nothing you can teach.

"With me having a lot of success in this league, I think guys will respect that. But at the same time I'm going to lead by example. I'm going to gain my respect by playing harder and going out and trying to win games every night."

I asked Jackson how he could help turn around a fractured locker room, one divided enough that Bucks point guard Brandon Jennings said near the end of last season that some guys didn't want to win.

"Whatever it takes, if it takes a slap, a fight," Jackson said. "We're here to win games. This is not high school and we're not doing any babysitting. We have to be on the same page to win, not just the players but the coaching staff and the whole organization.
