He fell off because he waited too long in between releasing music.
He also tried to carry himself like a rapper who was dropping gems. On that 10 Pc. Mild tape, he tried to be introspective have "bars" and **** and ended up sounding like one of those dudes that get high and just be rambling.
He should have just kept making "turn up" music. But even there, why would we need him for that when we have other rappers who do it much better?
Hope he at least charges 10k for the interview where someone asks where it all went wrong, and puts it into a laundromat or sneaker shop or something.
