Luke Thomas from MMA Fighting has honestly had the most level headed point of view out of anyone else I have read or listened to in the MMA-sphere. If this whole USADA thing is going to work, there needs to be due process for the athletes. When you come right out and publicly say "they've been flagged for a potential violation", they are often times seen as guilty in the court of public opinion (especially someone with as shakey a past as JBJ). Once you get branded with the "doper" tag, it never really goes away.
As far as the whole "yeah but you should KNOW what you're putting into your body" argument...yeah, I get it...to a point. Truthfully, I can barely understand what I put into my body. Are these guys supposed to be chemists? Maybe someone like Jon Jones should be able to afford to have people around him who can explain what he can and can not take, but the average fighter can not.
If you're making the argument that he should have disclosed every supplement he was taking so USADA could let him know if it was OK, that makes a little more sense. Let's keep in mind that your average MMA fan (including myself) has had zero interaction with USADA, and have no idea of helpful or not helpful their offices may be in answering fighter questions. It's easy to forget that anti-doping agencies have a somewhat questionable history of integrity (just ask boxing fans about USADA).
The bottom line is this:
1) Jones was guilty in the court of public opinion before any real evidence became clear. Is his personal history poor? Yes. Does this mean that he is automatically guilty? No.
2) Fighters deserve due process.
3) None of us REALLY know anything.
4) None of this renders moot the fight that Jon Jones is arguably the greatest talent that this sport has ever seen.
I'm always torn on Luke Thomas. He does tend to have level headed and logical takes, and I enjoy his podcast. But he also seems quite the fan of himself and only willing to interact with his "fans" if it benefits him in some way.
