I think you're forgetting that Spencer's gene pool includes a parent who was an Olympic medalist in a grappling sport. He couldn't possibly come from better genetics.
My two cents. If I could just bestow an attribute onto a wrestler or any athlete for that matter I would focus on body awareness, balance above strength, endurance, explosiveness etc. To be sure all is well of these qualities are important, but almost anybody can develop the necessary strength and endurance. What separates the best are there ability to feel and react instinctually. This could get me on a long diatribe, but I think the focus of a lot of youth sports training is misdirected. In my opinion if you want instinctual, creative athletes need less structure and more play. Coaches need to allow and encourage guys to try stuff. Most of training should be low pressure environment where failure is okay. I've seen coaches at times criticize their kids when they try a new skill and it doesn't work because they are focused on the result. This is the real challenge because obviously you want to correct flaws but if you're not careful you discourage development. Diatribe over.
If what you're trying to say is it doesn't matter what shape or size you are you can become a successful wrestler, then I agree.
