This summer saw one of the most eventful NBA offseasons of all time.

Kevin Durant demanded a trade and for his coach and general manage to be fired; All-Stars Donovan Mitchell and Rudy Gobert, among others, were dealt for record-setting packages; Celtics coach Ime Udoka was suspended for the season; Suns owner Robert Sarver said he will sell his team ... and the list goes on.

But after four months of drama, the 2022-23 NBA season is here. The Celtics and 76ers tip off at 7:30 p.m. Tuesday at TD Garden. (See the full Celtics schedule here.)


Here’s everything you need to get ready for the NBA season.

How to watch the Celtics

Most games will be available locally on NBC Sports Boston. As one of the league’s most high-profile teams, the Celtics will find themselves on national TV more often than most; they’re scheduled for 26 appearances this season.

Matchups against other top teams may be found on TNT (including Tuesday’s season opener), ESPN, and ABC. Some national TV games will be broadcast simultaneously on NBC Sports Boston.

The full Celtics schedule, with TV info for each game, can be found here.

What’s new with the Celtics?

Aside from Joe Mazzulla’s appointment as interim head coach in the absence of Udoka, the Celtics have had little roster turnover.

The biggest addition is guard Malcolm Brogdon, acquired from the Pacers in exchange for several players and a 2023 first-round pick. The 2016-17 Rookie of the Year, Brogdon gives the Celtics a massive upgrade in backcourt depth and will likely be deployed as an overqualified sixth man.

Summer signee Danilo Gallinari is likely shelved for the season after a second ACL tear in his left knee.

The only other significant newcomer is forward Blake Griffin, inked to a veteran minimum deal last month. Far from his days as a high flyer in Los Angeles, Griffin seems willing — like Brogdon — to embrace his role as a versatile depth piece.


It also may be worth keeping an eye on sharpshooter Sam Hauser, expected to play a much more significant role after largely plying his trade in sparse bench minutes and the G League last season, and Haverhill’s Noah Vonleh, a former first-round pick who managed to latch on with his local team after training camp.

Around the league: new faces, new places

Here are some of the biggest offseason movers:

Donovan Mitchell, Cavaliers One of the league’s best volume scorers got his long-awaited change of scenery, landing with a young, exciting Cleveland team. Dealt by the Jazz for a package around Collin Sexton, three first-round picks, and a pair of pick swaps, Mitchell joins Darius Garland, Evan Mobley, and the upstart Cavaliers on one of the league’s must-watch teams for NBA League Pass aficionados.

Rudy Gobert, Timberwolves Nobody wrangles first-round picks quite like Danny Ainge, who managed to land a market-resetting package for the Frenchman in the summer. Minnesota had to cough up four future first-round picks, a pick swap, and five players (largely for salary-matching purposes) to add Gobert as the Jazz go full speed ahead on a tank and the Timberwolves piece together a frontcourt with Gobert and Karl-Anthony Towns.

Jalen Brunson, Knicks — The only big mover in free agency, Brunson cashed in on an excellent playoff run — averaging 27.8 points in a first-round series against the Jazz to keep the Luka Doncic-less Mavericks afloat, then staying hot to help them reach the Western Conference finals when Doncic returned — for a four-year, $104 million deal with New York.


Story lines to watch

Can Zion Williamson regain the form and finesse he showed during his second season?Sean Gardner/Getty

The return of Zion Williamson. When he is at his best, few players have flashed the level of dominance that Williamson did in his second season with New Orleans in 2020-21: a hyper-efficient 27 points per game, blending transcendent athleticism with size, strength, and touch inside. After missing all of last season with a foot injury, he is coming into 2022 apparently healthy and in excellent shape. Now, we’ll see if he can remind the league why he was such a hyped prospect.

The combustible Lakers. LeBron James & Co. imploded last season, as five near-certain Hall of Famers in the rotation weren’t enough to make even the play-in tournament. An offseason trade for Russell Westbrook predictably backfired, Anthony Davis couldn’t stay healthy, and James’s 19th incredible season in a row couldn’t pick up the slack. Add to the mix Patrick Beverley, a strong rotation piece but one with whom Westbrook has had issues for nearly a decade, and you have the NBA’s biggest boom-or-bust squad. Except, perhaps, for ...

The similarly combustible Nets. Kevin Durant and Kyrie Irving are two of the most talented offensive players in history and proven champions, but between Durant’s offseason trade request and calling for coach Steve Nash and GM Sean Marks to be fired, and Irving’s laundry list of issues far too long to get into here, it’s hard to know whether Brooklyn will be a title contender or a dumpster fire. One way or the other, it should be interesting.


Winless for Wembanyama? Next summer’s draft will likely feature a prospect carrying hype not seen since the James Sweepstakes in 2003. French phenom Victor Wembanyama has every GM in basketball salivating, as he combines shooting, ball-handling, interior scoring, and defense with a monstrous frame, listed by some at 7 feet 4 inches with an 8-foot wingspan. Expect a race to the bottom, as any team unsure of a playoff spot will likely move their chips to the center of the table for lottery odds instead.

Rule changes

The biggest rule change is one fans have wanted for years: harsher punishments to eliminate transition take-fouls.

Recent years saw an uptick in these fouls, with players grabbing opponents off the ball in transition to prevent a fast break. Now, a take-foul in transition will be met with a free throw for the opposing team, plus continued possession.

Otherwise, the most notable rule change comes with scoring procedure: If a score must be changed after a review — most often when determining whether a shooter’s foot was on the line for a 3-point shot or if he stepped out of bounds — a blue light will flash at halfcourt so the score can be changed at the next available opportunity. That could mean updating the score after a made basket instead of waiting for a timeout or other stoppage.


Championship odds

Despite a turbulent end to the offseason, Las Vegas still has the Celtics as title favorites — hovering between 5-1 and 6-1 at most sportsbooks. The Warriors and Clippers are close behind, between 6-1 and 7-1; the only other teams with better than 10-1 odds are the Nets and Bucks.
