Durant's reason for asking for a trade was simple: "I was more so worried about how we're approaching every day as a basketball team," he said. Those concerns were addressed, and in Brooklyn he stayed, with the Nets expected to joust with Boston, Philadelphia, Milwaukee, Miami and probably others in a very deep Eastern Conference.

"A lot of teams have a legitimate shot," said Hall of Famer Chris Mullin, now a television analyst for the Warriors. "I think that's really good for the league. A lot of teams have two and three stars, and if they get their chemistry right, they stay healthy, they figure out the right kind of basketball to complement their talent, then there are a lot of teams with legitimate aspirations."

LeBron James enters this season 1,325 points behind Kareem Abdul-Jabbar for the NBA's all-time scoring lead, and the Lakers — if they can stay healthy — figure to be much better than the 33-49 record they posted last year.

The Los Angeles Clippers have Kawhi Leonard back after a year off with a knee injury, just as the Denver Nuggets get Jamal Murray back from knee rehabilitation to join forces again with two-time reigning MVP Nikola Jokic. Phoenix has a core that has won more games than any team in the NBA over the last two regular seasons, though it enters this season with its franchise for sale as a result of owner Robert Sarver's conduct.

All those clubs, and a few others, plan on contending.

"Hopefully, we can take another step," Leonard said. "That's all I can hope for." The Celtics and Warriors took more steps than anyone last season, getting to the finals.

And then, they took steps back.

Golden State's preseason was turned on its head when Warriors forward Draymond Green punched guard Jordan Poole during a practice session, a story that got immeasurably worse when video of the incident was leaked to TMZ. Green was fined by the Warriors, took a few days away from the team, then returned last week.

That all came a few weeks after the Celtics suspended coach Ime Udoka until June 30 after an investigation found he broke multiple team rules and was involved in an improper relationship with a female member of the organization.

Udoka, a feel-good story after going to the finals in his first year as a head coach, is being replaced by 34-year-old Joe Mazzulla for this season as the Celtics chase an 18th championship, one that would break a tie with the Lakers for the most in NBA history.

"The great thing about this organization, the players that we have, and the season last year is we have a formula for what we know we need to do in order to get better every single day and get back to where we want to get to," Mazzulla said.

"As much as we can focus on that, we'll be in good shape." There will be surprises. There will be injuries, probably some trades, maybe some firings along the way and presumably even some tanking — whether teams call it that or not — with hopes of enhancing their odds of winning the lottery and being able to draft French teenage phenom Victor Wembanyama next June.

Other teams, like the Warriors, also are thinking about June. Not for the draft, but because that's when a champion will be crowned.

"We are on hopefully another nine-month journey," said Warriors guard Stephen Curry, the reigning NBA Finals MVP.

"And it's exciting. We're blessed to play this game at the highest level and understand that we still have an opportunity to win a couple more championships."
