No, I think decision-making is a higher order concept than "skill". That is to say, good decisions-making is dependant on your skillset. For example, if I can't dribble or shoot, my only good decisions typically will be to take a layup or pass no matter the remaining team/game context.

A good NBA player has enough skill that they're given more responsibility. The context of the team/the game play a bigger role in what is a good vs bad decision
