It wouldn't matter that he's 19 if he'd been training well enough... to pick a topical example, Ronda Rousey was in the Olympics after training from ages 12-17 (I think they said 12 during the last Strikeforce). On the other hand, there are those who train "martial arts" for decades and learn less than our friendly reviewer. We have more productive topics.
Edit: no Fake, I'm too dumb I guess...he's allegedly been alternating between judo and boxing for six years is all I get, that plus apparently the gym is full of 16-year-olds. Maybe being hit in the head in training is bad for me after all?
