I hate subjective assessments like these. None of us know, so what's the point in another "what do you think" thread. His traps are well developed, but his delts are not outside of what a natural athlete can achieve. I'd have to see a comparison of him a few years before to see if he had huge gains in his traps. As it stands, the volume of wrestling and grappling he does highly develops that area of the body so it stands to reason that he could possibly just have a genetic proclivity for large traps. Regardless, we don't have positive blood tests so it's a pointless fucking exercise to guess.
