I don't see how anything short of 2 years is possible.
Without them using the "fact" that he was "mostly clean"-- I didn't see how either.
But then I remembered the CSAC could have FULL jurisdiction on this matter, being that its a fight week test. It may have even been administered by the CSAC on behalf of USADA. Regardless, the CSAC did announce when this happened that they are taking jurisdiction.
Its at least 50/50 custody between the CSAC and USADA.
"Mostly clean" (passed 95% of tests essentially, fight camp tested clean) being silently considered behind closed doors is about all he has going for him. And that is most definitely something the CSAC can do without looking poorly, as long as Jones brings a great defense.
Overeem has done it. It can be done. Its been done. Granted it was the NSAC I believe in Overeem's case, it was still an example of how the process can go even when caught red handed. The NSAC said they accepted the fact Overeem fucked up and said they wished him well in his fight career. It was the biggest jerkoff fest anyone had ever seen. Go watch that hearing. Overeem's defense was terrible and his doctor he brought to testify has a conviction for felony domestic battery and may not have been licensed in Texas, and is a Mexican national to boot. The doctor testified he told him to inject a testosterone solution for backpain.
If that circus can get a pat on the back and a handshake from the Commission-- anything is possible. Again, this is assuming the CSAC is going to take full jurisdiction and in the event that the UFC is going to cosign the full jurisdiction going to CSAC.
