There are superstars in the NBA. There are role players and benchwarmers, and then there are X-factors.
To be considered a X-factor, a player must not only be able to take over a game at any given moment, but also possess weaknesses in their game that causes them to battle consistency issues.
After all, if these players didn't have weaknesses, they would probably be considered stars in the Association.
Nonetheless, nearly every team, if not all, has one of these necessities on their roster, as high-risk/high-reward players are essential to a team's success.
*Rank is not based on talent, but instead the potential risk and reward that comes with the player.
