With the free-agent frenzy of the 2019 class, the NBA’s landscape has completely changed. Here’s the top 10 storylines entering NBA training camps.

Lakers could be boom or bust

LeBron James’ prime years are slipping away. Hence, the urgency for the Lake Show to become a title contender is omnipresent despite not having a fully formed roster, a head-coaching hire that appeared odd in Frank Vogel and a recent losing culture. The superstar union of James, 34, and big man Anthony Davis will be heavily scrutinized. Though James may handle the PG role, savvy Rajon Rondo is on board, and the Lakers will take a gamble on center Dwight Howard returning to some semblance of “Superman.” Like the Knicks, the Lakers have missed the playoff six straight seasons. Knicks fans should root for Lakers turmoil to fuel Davis’ free-agent departure.

The Zion Show on Bourbon Street

Commissioner Adam Silver couldn’t have been thrilled the Pelicans won the lottery, zooming Zion Williamson into the league’s smallest market in a city where football reigns. Williamson will try to change that perception, but alarm bells went off in Las Vegas when he looked more than his 285-pound listing in his summer-league debut against the Knicks. That didn’t cause the earthquake, but it shut him down for the tournament with knee and back soreness after nine minutes. The most-hyped No. 1 pick since King James will be on national TV a franchise-record 30 times. He’ll visit the Garden on Oct. 18 in preseason — lighter we hope.

James Harden has a new/old partner

Watching Harden and his overdribbling/isolation game in the playoffs was tough to stomach. The Rockets have wisely broken up the core after flaming out against Golden State again. With the ferocious attacker Russell Westbrook in and Chris Paul out, maybe coach Mike D’Antoni can get back to his old speedball, move-the-rock ways. Westbrook and Harden made the Finals with Oklahoma City in 2012, but that was before the bearded wonder decided to become a one-man show. With Golden State no longer dominant, the Westbrook-Harden-D’Antoni troika could make The Finals if it clicks.

Kawhi tries to defend his title in La-La land

After leaving Toronto after a one-and-done championship, Leonard is going home to SoCal, believing he’s got a shot to win a third title with three different teams. When the tamper-fest was over, Paul George demanded a trade to the Clippers as requisite for Leonard signing there. Coach Doc Rivers only has to decide who plays small or power forward. Before a parade down the Sunset Strip, the Clippers have to solve a problem at point guard, manned by Patrick Beverley, solid on defense but mostly average. Maybe the PG-weak Clippers will look to trade for one of the Knicks’ stock.

Welcome to San Francisco, D’LO

The Warriors open their gleaming new arena in downtown Frisco, but with no longer a daunting roster. Kevin Durant passed up crossing the Bay Bridge for the Brooklyn Bridge. Klay Thompson, maybe their best player considering his defensive gifts, could miss the season with a torn ACL. Thompson is an old-schooler, and the bet is he is back for the playoffs. But until then, ex-Nets PG D’Angelo Russell, whom the Nets shipped in the Kevin Durant sign-and-trade, is in a massive spotlight trying to fill the role of backcourt partner to Thompson’s best friend, Stephen Curry. Good luck, Steve Kerr.

The strife-ridden Celtics massively underachieved last season, and even defector Kyrie Irving admitted he should have been a better leader. PG Kemba Walker has played on mostly losing teams in Charlotte but is a terrific talent, not an enigma and squarely in his prime. The Bronx product should fill the bill while Gordon Hayward returns to better form. However, the Celtics will have to fill Al Horford’s departure with ex-Knick strongman Enes Kanter. That hurts the pick-and-roll defense but will create awareness about the Turkish government in Boston.

Utah Could Be the Sleeper

The Grizzlies, to make room for their No. 2-overall draft pick Ja Morant, shipped veteran PG Mike Conley’s big contract to Utah, which needed tinkering after its first-round playoff implosion. Ricky Rubio is gone, and Conley attempts to steer the Jazz to title contention if he can connect with studs Donovan Mitchell and center Rudy Gobert. Adding sharpshooter Bojan Bogdanovich could also aid a Salt Lake City takeover.

Kristaps Porzingis Gets to Finally Stick it to Knicks

A more muscular-looking Porzingis tweeted last week: “The one thing you can control in life is your effort.’’ The other thing you can control is not getting back on the court for a regular-season game until after signing a $154 million contract. Porzingis admitted he had no intentions of returning last season for the Knicks. Now KP will break a 20-month absence in a Dallas uniform. If he emerges as a superstar off the bat and forms a scary tandem with Luka Doncic, Knicks president Steve Mills will have many sleepless nights.

Bradley Beal’s Future at Stake

According to sources, rampant turmoil existed in the Wizards front office before Tommy Sheppard was finally promoted to permanent GM after the draft and free agency. The Wizards could wind up as the NBA’s worst team, with John Wall possibly out for the season with an Achilles tendon tear. That could spark a massive rebuild and could prompt Sheppard to deal Beal before giving him a max contract extension. The Knicks should have interest.



Former No. 1 Pick Could Make Some Magic

Markelle Fultz’s two-year stint after being taken No. 1 in the draft was a colossal fail — ridden by either a mental block or a rare shoulder disorder that undermined his shooting form. The 76ers gave up on Fultz, and now he’s attempting in Orlando to avoid the ignominy of being the biggest No. 1 pick bust of all time. The Magic made the playoffs for the first time since 2012 last season. Sparked by the re-signing of underrated center stud Nikola Vucevic and Aaron Gordon’s evolution, they have lusted after a point guard the past couple of years. Fultz will be guided by underrated coach Steve Clifford, who couldn’t even land a job interview with the Knicks in 2018.
