Here's how I understand what happened.
Sonnen:
The first test (2 days before the fight) only tested for "foreign" testosterone levels. Apparently Chael felt he notified the proper people at this time of his TRT (testosterone replacement therapy).
Then he fights.
Then he gets popped for levels of synthetic testosterone that are WELL above normal.
A few days later, they re-test him, this time testing his ACTUAL testosterone level.
The tests come out as he is in the normal range (well, he's had 2 or more days at this point for his Testosterone to return to a normal state now)
The CSAC is absolutely dumbfounded by all of this.
They can't legitimately call him a cheater, because they never bothered to test his actual testosterone level before the fight.
But they all agree he fucked up by not telling the proper CSAC representatives and suspend/fine him based on that.
6 months, $2500.
That is how I understand it. Wether you choose to believe Sonnen is a cheater or not is your call.
Barnett:
Barnett is a piece of shit whose either not appeared or pushed his "hearing" date back 5 fucking times already. So he strolls in to the CSAC hearing and lo and behold, the CSAC has no interest in just handing him another pee-test cup and saying, "ready when you are Mr. Barnett... let's get that license out to you, PRONTO!" ... instead, the have some Attorney General (or lieutenant attorney general or something) whose ready to get some closure on their LAST go-around with Barnett....
a go-around that ultimately proved to be the very start of a chain reaction that completely destroyed an entire MMA organization.
Yeah, imagine Barnett's abject surprise when the CSAC wasn't willing to just let bygons be bygons over his last episode.... never mind that they weren't willing to let the fact that Barnett has pushed his date back with them 5 times and they probably weren't exactly pleased by that either.
So here he comes, shows up by himself, and they want answers.
"Oh my god! I had no idea it was going to be an interrogation! I need my lawyer present, first"
=
"Awww shit, I wasn't prepared for any of this, I was hoping you guys would all forget about that last time when I was caught being a fucking cheater. I'll need to have my lawyer write up some vague and ambiguous answers that don't say anything before I can answer any of their questions. I better come back when I have a whole 14 page document that says nothing."
Fuck Barnett... hands down the single worst thing ever in MMA and I hope he gets fucking blackballed out of MMA forever and I never have to see that piece of shit ever again.
There aren't many fighters that really make me want to flip the fuck out, but Barnett is by far the worst and a big hot button for me.
Fuck that faggot.
