Takes time for a tall SH to fill out. I give the kid credit for getting on stage in pretty good shape even though this is not the contest he is peaking for.
Either way, even if he does turn pro, he will wind up a 2-3 tier IFBB pro, if he even lives that long. No real future for him in competitive bodybuilding at the IFBB level. He should keep training, and keeping feeding people bullshit about drug regimens. Other than that, he will be a nobody in the sport.
