guys like pujols, tebow etc.. are easy to see they use a lot of hgh
guys like derek rose, dwight howard etc.. are easy to see they are using peds... lebron shows lots of signs, wade has the look of a moderate image (unfair but i'm using stars among the more obvious rather than name off lesser knowns)
but Braun is a surprise because while he isn't skiny, he isn't swolen up beyond the frame a guy who just works fairly hard could achieve and he is such a fluid "natural" ballplayer...
90% will experiment with steroids, or hgh , or peds at some point from HS-College-Pros, but you like to think most grow out of that or relegate it to cycles during training.
Braun is surprising.
