MMA Prodigy or Too Much Too Soon?

I'm not exactly sure how I feel about this. He's obviously got great skills (especially for a kid his age) but I can't help but think it's another example of youngsters in America specializing too soon in sports activities.

It's my understanding that in most other parts of the world, the youth are encouraged to try a variety of sports and increase their general exposure to athletics. This is an advantage in keeping their interest piqued and it also develops more well-rounded physical attributes. "Jack of all trades, master of none" would be a great motto for all parents of young athletes to adopt, at least during their most formative years.
