The coach ain't help out, so I call my own shots
Cole has metaphorically been “on the bench” for a long time, so he decided to be his own boss in order to get the spotlight he deserves. His mentor/coach Jay-Z also hasn’t helped him and not taken paying much of an interest in his career despite signing him. So he has to do things himself ‘call his own shots’
He uses a basketball theme like this in many of his songs; in school he was cut from the basketball team.
This could also refer to his father, who is supposed to teach you important things in life. He didn’t have his dad, so he had to teach himself these things instead.
