In this Pod cast with Chael he says (about 30min) that Jon Jones should just man up and admit to taking PED's. Hey I agree it gets pretty infuriating hearing all these bullshit stories when we know pretty much for sure they are taking. BUT.... once you own up then there's going to be repercussions. I think these guys are protecting their team, their trainers. Surely they are all in on it in some way, if someone actually admits to breaking the rules then there will have to be a full investigation and everyone is going down. I'd almost go as far as UFC etc. actually encourage the guys to make up these phony stories as the best route once caught.
