Cleveland Cavaliers star LeBron James appeared to be in rare form during a pickup game in California. James posted a video of himself playing basketball and throwing down dunks in UCLA’s practice facility Wednesday.

This summer, James posted multiple Instagram videos of himself playing basketball with other basketball stars like Carmelo Anthony and Kevin Durant last Tuesday. This time, he uploaded footage of himself blowing by defenders and performing rim-bending dunks during a game of pickup game of basketball.

James played alongside fellow NBA players who included Nick Young of the Los Angeles Lakers, Aaron Gordon of the Orlando Magic and Victor Oladipo of the Indiana Pacers. LaVar Ball’s second-oldest son, UCLA freshman LiAngelo Ball, also played in the exhibition game.

"My love for this game is insane and drive me crazy," James wrote on Instagram Wednesday.

He added, "Nothing to me is better than the process of feeling uncomfortable as u try and push to improve on your skill/talent. I have no ceiling and I refuse to fall into the trap of complacency!"

In the video, LiAngelo Ball, wearing a red T-shirt, witnessed James, in a bright green shirt, throw down a ferocious dunk. James could also be seen beating his defenders off the dribble and tossing assists to his teammates.

In a separate training video posted Tuesday, James could be seen running and dunking at both ends of the basketball court.

Needless to say, James has been busy strengthening his athletic ability this summer. His Cavaliers have also been working to bolster their roster with Tuesday’s swap of All-Star guard Kyrie Irving for All-Star guard Isaiah Thomas.

Irving, whose trade request went public last month, seemingly forced the team to relocate the star guard. Meanwhile, James, whose future with the Cavaliers remains uncertain, remained mum after the trade until Thursday.

Images of Celtics fans burning Thomas’ old Celtics jersey surfaced on social media Tuesday. Fans also destroyed former Utah Jazz forward Gordon Hayward's jersey in July when he announced his signing with the Celtics.

James, seemingly infuriated over the idea of distraught fans burning NBA players’ jerseys, took to social media and defended his fellow NBA stars. In a series of five tweets, the All-Star forward defended his new teammate Thomas, who Boston traded to the Cavaliers in exchange for Irving.

"The burning of the jersey thing is getting ridiculous now! The man was traded. What do u not understand? And played in a game after sister tragic death," James tweeted in defense of his new teammate.

"Gordon Hayward paid he's dues as well and decided to do what's best for him and family. Put in the work, got better, became an All-Star, etc!!," James tweeted in defense of Hayward.

James argued that if the aforementioned players weren’t any good, fans would be asking for teams to trade them.

He added, "If these guys weren't good, u guys would be the first to say 'get them up out of here.' Man beat it! When we decide to do what best for us it's a cowardly traitor, etc but when it's on the other side it's business huh!?!?"

"Man do what u feel is best for your profession, love, family, happiness and continue to #StriveForGreatness #Salute," he concluded.

Thomas became the face of the Celtics franchise since he joined the team in February 2015. The Celtics also packaged role players Jae Crowder and Ante Zizic and an unprotected first-round pick in the Cavaliers deal.
