Tons of people have bigger body parts. Overall, looking at the total package, Adonis is delusional to assert he's superior to a world class athlete.
Adonis is a good guy but is prone to these odd tangents, LOL! Nothing we say will stop the barrage of pics/comparisons yet to come.
Being a world-class athlete does not make you muscular. These guys usually don't train for looks but for speed , strength .. whatever.
If you just compare their bodies from a bodybuilding point of view it's pretty obvious that TA is smoking him.
Even in that first picture he does not look impressive at all .. all of the other pictures show a guy who's at most slightly better built than the average (black) male.
I don't know this Owens guy but I guess he's kinda tall but I think Adonis is not short either so I think he'd dwarf him standing side by side.
