Celtics president Danny Ainge made his weekly appearance on The Big Show Wednesday. Here are some highlights from the interview. To listen, click here.

The idea of the NCAA tournament expanding to 96 teams:

“I don’t think they should. Sixty-four is good, I think it’s just right. Good the way it is.”

Why the team is playing so well at this point (won five of last seven):

“I think it’s mostly health. I feel good about this team. I think we’re finally there. Just a question of Doc getting the pieces to fit. I feel like our team … I feel that the hope is there. You can see that they really want it.”

Is he concerned about not getting the 3 seed in the Eastern Conference playoffs?

“No, no. It’s just not the focus. I follow it each day, but we aren’t talking about it internally. [We are] focusing on what we need to do to go out and play.”

Why the team has played so well on the road (second-best record in the NBA) but struggled somewhat at home (13th-best record):

“No I can’t [figure it out]. We haven’t been as good a team. We had three or four Gino games at the Garden, which we haven’t had in a while.”

On the downfall of Antoine Walker:

It’s hard to imagine. $110 million …  too many guys in sports with nothing to show for it. A high percentage. With Antoine [the entourage consists of] people he chose to pay, he wanted to. He needed an entourage, wanted to show that he has this money, go gamble and party. He’s a very generous person as well. Where does $110 million go?”

If the entourage scene is still as prevalent as it was in Walker’s early years:

“A little less in the last few years. It was the thing to do. Guys parking cars, washing cars, cook. I don’t know where $100 million goes. The story of Kenny Anderson [he] made $60 [million], $70 million in his career. Rumeal Robinson living on the street, he made $20 million.”

If the Celtics talk to the young players about stories like Walker:

“We’ll make sure all the players will see that tape.”

On the highlights of Walker playing basketball in Puerto Rico:

“I’m glad he’s posting up, not shooting 3′s.”
