The wrestling thing is bugging me. Isn't there usually a OMG great wrestler on the show? I don't see any on this season. Isn't great wrestling one of the big things for American based MMA fighters?
When I think of a likely skill for a fighter based on nothing but country origin I think
USA - Wrestling
UK - Boxing
Brazil - BJJ
Of course not always the case but wrestling is very big in American school's sports programs.
