You don't believe Braun is a juicer? really? Do you mean you don't believe he is currently juicing, or that he never did?
It's impossible to defend him, don't get me wrong. But I dunno, there's stuff with Braun that just doesn't entirely add up with me. For one, since he was a high school and college player he's always been a pretty decently built guy and he's never had odd growth spurts or anything odd. His growth has been pretty natural as far as I can see, and he's never had any ridiculous power explosions or anything like that like what A-Rod or other big name juicers had (Braun's pretty much always been a top tier player in whatever place he played). And he's remained a top tier player since that whole story got leaked (presumably when he'd now be off whatever juice he was on).
In my mind he's either not on the juice or has been a juicer since he was in his teens. It's entirely possible that he hopped up on something to bounce back from one of his minor injuries, but a lot of his injuries were almost too minor to justify it in my opinion. Like I said, defending Braun is pretty hard to do at this point but something just doesn't add up with it all in my mind - plus MLB's side of the whole Braun ordeal was just as sketchy as Braun's side of the story.
Rickie Weeks in my opinion looks like the prototypical juicer though. He's had to bounce back from a few pretty rough injuries and he's bulked up a ton since he came up from the minors. I wouldn't be surprised if Hart was on the juice for a similar reason, Hart seems to spend every first month of the season on the DL (it's like clockwork at this point) so I wouldn't be surprised if he was doing whatever he could to get back on the field.
