Mario Hezonja plays with a lot of emotion, which at times takes him out of his game. That could be an issue coming into the NBA next season as a rookie. From Terry Foster of The Detroit News:

"Most mock draft experts believe the Detroit Pistons will select Croatian shooting guard Mario Hezonja with the eighth pick. He'd be a good fit. The problem is, other teams ahead of the Pistons are doing extra homework on Hezonja, and he might not be there when the Pistons select. Teams behind the Pistons could also trade up. ... European scouts say Hezonja not only wants to dunk in your face but he wants you to know that he dunked in your face. He plays with a brashness and high emotion that can get him into the game -- but also at times, get him off his game. He has been compared to Kobe Bryant because of his competitive nature. He hates to lose and he chastises teammates that he believes are not playing up to their potential – something Bryant is well known for doing. Yelling at teammates won't play on the Pistons team. It won't make them play harder and they would be more likely to turn on Hezonja."
