Dallas Mavericks star Luka Doncic has left little doubt that he's a generational superstar. The 22-year-old has already done amazing things for the Mavs, and he's just had three full NBA seasons under his belt.

But if there's one thing that's been rubbing fans the wrong way about Luka Doncic, it's his constant complaining to the referees. The Mavs star acknowledged as much during the NBA season, and now even during the Olympics Doncic spoke out about his behavior in his last two contests.

“We were a little bit too emotional in both games – especially me,” the Mavs star admitted. “I have got to learn from that and it is not the way I should be behaving. We played for our country of two million people and we wanted to get them that medal. We were away from our families and you can trust me that we really gave it our all.” 

Luka Doncic was Slovenia's MVP throughout the Olympic games and did everything he could to compete against rosters filled with NBA players. Interestingly enough, Doncic has a somewhat similar situation on the Mavs, who rely heavily on his production without a clear-cut star running mate by his side.

As Doncic matures and gets better teammates throughout his career, his constant complaining should subside soon enough.
