CLEVELAND, Ohio -- Some of the NBA's best gathered on the campus of UCLA for a summer workout Tuesday.

LeBron James. Kevin Durant. Kawhi Leonard. Cedi Osman.

Yes, that's right. There was Osman -- the second-year Cavaliers swingman -- getting photographed and putting in work alongside a few of the league's premier small forwards.

There were also coaches from other teams, including former Cavaliers assistant Phil Handy who joined the Toronto Raptors this off-season after not having his contract renewed in Cleveland. It was Handy who posted the group photo on his social media.

"Work is work," Handy wrote. "It don't matter what team we represent, the NBA is family. True professionals all trying to perfect our craft."

As for James and Osman, the two became close this past season in Cleveland, with Osman eventually earning a spot in James' post-practice shooting group. Throughout the regular season, James often spoke highly of Osman's basketball IQ and professional approach despite playing time that fluctuated.

Shortly after James' departure for Los Angeles this summer, Osman wrote a heartfelt message to James and posted it to Instagram.

"Some people bring out the worst in you, others bring out the best. And there are remarkably rare ones who just bring out the most of everything that even you don't know that you have," Osman wrote. "They build you up. They make you feel alive. They make you feel strong. They make you feel indisputable. From the first moment we met, you've always been that rare one for me, King.

"I don't believe in coincidences. I choose to believe my path crossed with you for a reason. And that reason will be uncovered as I continue to walk through. Please accept my highest gratitude for your support and appreciation for your inspiration. I'm truly blessed to have been surrounded by your charm."

Osman spoke numerous times throughout his rookie year about how thrilling it was to not only be in the NBA, but to compete for a title and be welcomed by James.

"For me it's really amazing being on this team," Osman said in December. "We have great players, great coaches, this is a championship team. And from the first day when we came in as new players, LeBron was saying we have to live as a champion from the first day."

It's been a busy, basketball-filled summer for Osman, who played for Turkey in the FIBA Basketball World Cup 2019 European Qualifiers before joining the Cavaliers in Las Vegas for summer league. It's all part of Osman's plan to show the Cavs he's ready for a bigger role during the post-LeBron era.

Working out with James, Durant and Leonard can't hurt.
