Any one that is smart enough to truly want to become a better fighter. Stupid national pride be damned they don't get that quality of wrestling training in brazil and it's historically been the hole in the skill set of fighters coming out of brazil.
Although every discipline is important, they don't really need "that quality of wrestling training"
when they can have "that quality of Jiu Jitsu training"
instead. Apart his recent win over Shogun's counterfeit copy, historically
, Chael himself knows very well these mentioned skill set holes in Brazilian fighters didn't prove enough to grant him a win over the Braziliam competition he fought against, since he tapped to Babalu, Paulo Filho, Maia and Anderson.
