Yes, but let's not ignore the facts:
Brazilian fighters are 2.5 times more likely to fail a USADA test than an American fighter.
Brazil:
- 121 Total Athletes
- 18 Violations
- 18/121 = 14.88%
United States:
- 404 Total Athletes
- 24 Violations
- 24/404 = 5.94%
[For comparison: No country with more than 1 violation has a higher percentage than Brazil. The closest are Russian Fighters who fail at 11.11%, then the huge drop to the US at 5.94%, and Great Britain at 5.56% - Otherwise all other countries only have either 0 or 1 Violation]
You also can't ignore that Brazilian fighters win % has dropped more since USADA started than US fighters. Pre-USADA Brazilian fighters won 2 out of 3 fights, since USADA they barely win 1 out of 2.
