I agree that based on his skill set he has a higher bust potential and if you picked him to say you predict he will bust, not that he already is one... I can see the rationale. But for anyone to say he's already a bust is very premature.
He also has the floor of a plus defensive CF with burning speed, power potential and a good eye as evidenced by his increasing walk rate. Even if he can't contact as well he will still likely make the big leagues barring injury as a 4th OF/pinch runner, barring further injury issues.
So at that point I guess it depends on one's definition of bust.... making the majors but nowhere near your ceiling, or just never making it at all and getting punted, like Jake Anderson
