The kid can crack. If he fought like Rios, he'd have more KOs. He doesn't. He's a proven boxer with an extensive and impressive amateur record.
I don't think he goes into fights looking for a KO. If he hurts a guy, he's shown that he can finish. He shows patience and poise in the ring. He may not collect as many KOs fighting this way, but it will sure lengthen his career in the long run.
