With all due respect, Helwani is an idiot.
For Jones to fight at MSG would mean him only getting a 1 year suspension. That is half of what Frank Mir got for the same substance, despite it being his second offence...
The only way that could happen (a 75% reduction in penalty) is if they found a non-high-risk supplement contaminated with Turinabol.
We already know that Jones had every single supplement he took (and another ten on top) and nothing was found, which is not surprising. In the entire history of a USADA there is not a single non-high-risk supplement ever found contaminated with turinabol.
If Jones went to arbitration and got 1 year wouldn't surprise me to see both USADA and WADA appeal it to CAS
