**** at that pic, 5-6 weeks he lost that much muscle. This pic has convinced me was juicing. Lebron was massive and I mean muscle wise and FYI body builders go on a no carb diet as they get close to their show and don't lose their muscle like that.
My guess is that you were already convinced he was juicing, and that the picture is providing some serious confirmation bias.
Also, the fact that none of the posters that are crying "steroids" seem to have any idea of what the new NBA drug policy is going to be is a bit concerning. Possibly because there isn't a new policy coming next season, but you want to believe that it's real in order for it to "prove" this LeBron theory.
I'm agnostic as to LeBron's steroid use, by the way. Either he's on them or he isn't, but I'm not going to let a crude series of "well of course he is" and some cursory pictorial evidence be the deciding factor. Otherwise I'd probably believe in chemtrails and aliens and a faked Sandy Hook, too.
