When a skill is not active, it will be greyed out.

The HUD shows the name of the player that is being controlled, the Signature Skills he possesses and his basic stat line. The HUD will remain visible as long as the user does not press Up on the D-Pad again. The user can bring up the Signature Skills HUD (located in the upper left-hand corner in a single player game and in both the upper left-hand and right-hand corners in a multi-player game) by pressing Up on the D-Pad. Signature Skills are activated automatically in the appropriate situation. Beginning with NBA 2K15, Signature Skills were replaced by Badges, which grant players similar skills. Six new signature skills were added in NBA 2K14. Both star players and role players with particular standout skills make use of Signature Skills. They are intended to provide differentiation between players and expand upon the existing attribute and tendency system, as players with Signature Skills have added abilities and a greater chance of performing certain situational actions on the court. Signature Skills are a gameplay mechanic in the NBA 2K series, introduced in NBA 2K13.
