The overwhelming majority of NBA teams are willing to put up with a difficult player on their roster...provided that he's extremely talented on the basketball court.
Included in that "difficult" designation are those players who often exhibit diva-like tendencies and/or those who don't fully embrace the philosophy of team basketball. And then there are the "headcases": the unique group of individuals whose attitude and approach to the game holds them back from reaching their full potential.
For these players, their maturity—or, specifically, the lack of it—often overshadows their accomplishments on the court. And if any of them ever learn how to harness their emotions in the correct way, they could completely alter the entire narrative of their careers.
